Blue Fruit Flies: What Are They & Should You Worry?

The persistent buzz of tiny wings around your fruit bowl – a sound familiar to almost every household. Fruit flies, those miniature acrobats of the kitchen, are a ubiquitous nuisance, drawn to the sweet scent of ripening produce. Their ability to seemingly appear from nowhere and rapidly multiply makes them a frustrating problem for homeowners and businesses alike.

But what if these already unwelcome guests took on an unusual hue?

The Intriguing Question: Are "Blue Fruit Flies" Real?

The very notion of “blue fruit flies” sparks curiosity. Are they a distinct species, a bizarre mutation, or simply a trick of the light, fueled by online speculation? The internet is rife with anecdotal accounts and blurry images, leaving many to wonder: do these sapphire-tinted pests genuinely exist, or are they a product of mistaken identity and viral misinformation?

Distinguishing fact from fiction becomes crucial in understanding the scope of the issue.

Setting the Stage: Exploring the Unknown

This exploration delves into the intriguing question of "blue fruit flies." It will examine the potential origins of this phenomenon, considering possibilities ranging from genetic anomalies to environmental influences.

We will also address the possibility of misidentification, separating verified occurrences from unsubstantiated claims. By investigating the plausibility of blue fruit flies, this analysis aims to provide clarity and context to a topic shrouded in mystery.

Thesis: Reality, Causes, and Concern

This analysis contends that while true “blue fruit flies” may be rare, the phenomenon likely arises from a combination of genetic mutations or dietary influences on common fruit fly species, coupled with instances of misidentification.

Ultimately, while the existence of blue-tinged fruit flies may warrant curiosity, the level of concern should remain consistent with that of any other fruit fly infestation – a matter of hygiene and potential food contamination, rather than a novel threat. The focus should remain on the control and prevention of fruit flies in general, regardless of their color variations.

The internet’s curiosity is piqued. Yet, to truly understand the potential of a color variant, we must first ground ourselves in the fundamentals. What exactly are fruit flies, and why are they so pervasive?

Understanding Fruit Flies: A General Overview

Before dissecting the mystery of "blue fruit flies," it’s crucial to establish a solid understanding of these insects in general. This foundation will allow for a more informed assessment of any claims or anomalies related to their coloration.

General Characteristics

Fruit flies, often encountered buzzing around overripe bananas or neglected wine glasses, are small insects belonging to the Drosophilidae family. Their size is a key identifier: typically only 3-4 millimeters long, roughly the size of a sesame seed.

Their appearance is characterized by a rounded body, large, often red eyes (though color can vary depending on species and mutation), and short, bristly antennae. They possess a yellowish-tan base color, though darker stripes or markings are often present on the abdomen.

Behaviorally, fruit flies are drawn to fermenting sugars and decaying organic matter, which serve as both food sources and breeding grounds. They exhibit a rapid, erratic flight pattern, making them a frustrating presence in kitchens and pantries.

Their habitat is closely linked to the availability of these resources, making homes, grocery stores, and orchards prime locations for infestations. Fruit flies are most active in warmer temperatures.

Common Species

While numerous species exist within the Drosophilidae family, a few are particularly prevalent in human environments. Drosophila melanogaster, the common fruit fly, is perhaps the most well-known and widely studied species. It is frequently used in genetic research due to its short lifecycle and easily observable traits.

Drosophila suzukii, also known as the spotted wing drosophila, is an invasive species that has become a significant agricultural pest. Unlike most fruit flies, D. suzukii females possess a serrated ovipositor, allowing them to lay eggs in undamaged, ripening fruit. This characteristic distinguishes them from other common species and causes substantial damage to crops.

Other less common, but potentially encountered, Drosophila species may include those that prefer specific types of fruit or decaying matter. Proper identification often requires closer examination and, in some cases, expert analysis.

Rapid Lifecycle and Infestations

One of the most significant factors contributing to fruit fly infestations is their remarkably short lifecycle. Under optimal conditions (warm temperatures and readily available food), a fruit fly can complete its development from egg to adult in as little as 7-10 days.

A female fruit fly can lay hundreds of eggs during her relatively short lifespan, typically near or on the surface of fermenting food sources. The eggs hatch into larvae (maggots) that feed on the decaying material.

These larvae then pupate, forming a hardened casing from which the adult fly emerges. This rapid reproduction cycle allows populations to explode quickly, leading to noticeable infestations within a matter of days. Understanding this lifecycle is critical for implementing effective control measures and preventing recurring problems.

The Truth About "Blue Fruit Flies": Fact or Fiction?

Having explored the general characteristics and lifecycle of common fruit flies, we now turn our attention to a more specific, and perhaps more puzzling, claim: the existence of "blue fruit flies." Are these insects a genuine, documented phenomenon, or are they simply a product of misidentification, wishful thinking, or even online misinformation? This section delves into the evidence, potential causes, and likelihood of encountering genuinely blue fruit flies.

Blue Fruit Flies: Species or Variation?

The first crucial question is whether "blue fruit fly" refers to a distinct species within the Drosophilidae family, or merely a color variation within an existing species. Currently, there is no recognized species officially classified or scientifically documented as "blue fruit fly." This suggests that any observed blue coloration is more likely a variation within a common species.

This variation could stem from several factors, which we’ll explore below, but it’s important to emphasize that a widespread, naturally occurring blue species simply hasn’t been identified to date. The phenomenon requires dissecting to understand any claims or reported sightings.

Potential Causes of Blue Coloring

If blue fruit flies aren’t a distinct species, then what could account for reports of their existence? Several possibilities exist, ranging from genetic anomalies to environmental influences.

Genetic Mutation: A Chance Anomaly?

Genetic mutations can lead to unusual color variations in many organisms, including insects. A mutation affecting the production or deposition of pigments could, theoretically, result in a bluish hue in a fruit fly.

However, it’s crucial to understand that mutations are relatively rare and often detrimental to an organism’s survival. A mutation that results in blue coloration might also make the fly more conspicuous to predators, or impair its ability to find food or mates.

Therefore, while a genetic mutation causing blue coloring is plausible, it’s also likely to be an uncommon and potentially short-lived phenomenon.

Environmental Factors: The Role of Diet

Another possibility is that diet or other environmental factors could influence the color of fruit flies. Certain pigments present in their food source might, in theory, be incorporated into their bodies, resulting in a temporary color change.

However, the extent to which diet can significantly alter the overall color of a fruit fly is debatable. While dietary changes can influence subtle variations in existing coloration, a complete shift to a distinct blue hue seems less likely without a contributing genetic component.

Further research would be needed to determine if specific food sources could induce such a dramatic color change.

Misidentification: A Case of Mistaken Identity

Perhaps the most likely explanation for the "blue fruit fly" phenomenon is simply misidentification. There are numerous small, bluish-grey insects that could be mistaken for fruit flies, particularly by those unfamiliar with entomology.

Some examples include:

• Aphids: Certain species of aphids can exhibit a bluish or greenish-grey coloration and are often found on plants, potentially leading to confusion.
• Thrips: These tiny, slender insects can also appear bluish-grey under certain lighting conditions and are known to infest fruits and vegetables.
• Small blue-winged insects: There are several species of small flies and wasps that have blue iridescent wings or bodies, which could lead to misidentification, especially during a fleeting glimpse.

Close examination and accurate identification are crucial to avoid misattributing blue coloration to fruit flies when another insect is the actual culprit.

Addressing Misinformation Online

The internet can be a breeding ground for misinformation, and the topic of "blue fruit flies" is no exception. Exaggerated claims, anecdotal evidence, and unverified images can quickly spread online, creating a distorted perception of reality.

It’s essential to approach online information about blue fruit flies with a healthy dose of skepticism. Always verify claims with reputable sources, such as scientific publications, entomology experts, or university extension services. Be wary of sensationalized headlines, blurry images, and unsubstantiated accounts.

By critically evaluating the information available and relying on credible sources, we can separate fact from fiction and gain a more accurate understanding of the "blue fruit fly" phenomenon.

Having established that "blue fruit flies" are unlikely to be a distinct species and are more plausibly a rare variation, it’s crucial to accurately identify the common fruit fly species that infest our homes. Proper identification is the first step in effective control and prevention. This section serves as a practical guide to differentiating the usual suspects from other small insects, minimizing misidentification, and understanding the characteristics of the most prevalent fruit fly species.

Common Fruit Fly Species: Identification Guide

Distinguishing between different types of fruit flies and other similar insects is vital for effective pest management. While the "blue fruit fly" remains elusive, encountering common species like Drosophila melanogaster and the invasive Drosophila suzukii is a near certainty. Knowing how to tell them apart can significantly impact your approach to controlling and preventing infestations.

Drosophila melanogaster: The Common Fruit Fly

The Drosophila melanogaster, or common fruit fly, is the species most frequently encountered in homes. These tiny insects are drawn to overripe fruits and fermenting substances. Accurately identifying them is essential for targeted control measures.

Appearance

Drosophila melanogaster are small, typically 3-4 mm in length. They have a tan or light brown body with red eyes. A key identifying feature is the presence of transverse dark bands across their abdomen.

Habitat

As their name suggests, common fruit flies thrive in environments with decaying fruit and vegetables. You’ll often find them near fruit bowls, garbage disposals, and anywhere fermentation is occurring.

Behavior

They are active during the day and exhibit a characteristic erratic, hovering flight pattern. Their rapid reproduction rate means that a small number of fruit flies can quickly become a major infestation.

Drosophila suzukii: The Spotted Wing Drosophila

Drosophila suzukii, also known as the spotted wing drosophila (SWD), is an invasive species that poses a significant threat to fruit crops. Unlike other fruit flies, D. suzukii can lay eggs in undamaged, ripening fruit, causing substantial economic damage.

Appearance

D. suzukii is similar in size to D. melanogaster, but there are key differences. Male D. suzukii have a distinct black spot on each wing, hence the name "spotted wing drosophila." Females lack these spots, making them more difficult to identify. However, they possess a serrated ovipositor (egg-laying organ) that allows them to pierce the skin of ripening fruit.

Damage to Fruits

The damage caused by D. suzukii is considerable. By laying eggs in ripening fruit, they introduce bacteria and fungi, causing the fruit to rot from the inside out. This can lead to significant losses for fruit growers and backyard gardeners alike.

Identifying Features

Beyond the wing spots in males, the best way to identify D. suzukii is to examine the fruit for small oviposition scars. These scars are tiny punctures in the fruit’s skin where the female has laid her eggs. Infested fruit will often soften and collapse quickly.

Differentiating Fruit Flies from Other Small Insects

It’s easy to mistake fruit flies for other small insects that may be present in your home. Accurately distinguishing between them is crucial for implementing the right control measures.

Common Look-alikes

Some common insects that are often confused with fruit flies include:

• Fungus Gnats: These are small, dark-colored flies that are often found near houseplants. They are more slender than fruit flies and have longer legs.

• Drain Flies (Moth Flies): These flies are small and fuzzy, with rounded wings that resemble moth wings. They are often found near drains and sewers.

• Phorid Flies (Humpbacked Flies): These flies have a distinctive humpbacked appearance and a jerky, rapid flight pattern. They are attracted to decaying organic matter.

Key Distinguishing Features

To differentiate between fruit flies and these other insects, pay close attention to the following characteristics:

• Size and Shape: Fruit flies are typically smaller and more compact than fungus gnats or drain flies. Phorid flies have a distinctive humpbacked shape.

• Color: Fruit flies are usually tan or light brown, while fungus gnats are darker.

• Flight Pattern: Fruit flies have an erratic, hovering flight pattern, while phorid flies have a jerky, rapid flight.

• Habitat: Fruit flies are typically found near fruit and fermenting substances, while fungus gnats are found near houseplants, and drain flies are found near drains.

By carefully observing these features, you can accurately identify the insects in your home and take appropriate action to control them.

Having established that "blue fruit flies" are unlikely to be a distinct species and are more plausibly a rare variation, it’s crucial to accurately identify the common fruit fly species that infest our homes. Proper identification is the first step in effective control and prevention. This section serves as a practical guide to differentiating the usual suspects from other small insects, minimizing misidentification, and understanding the characteristics of the most prevalent fruit fly species.

Why Fruit Flies Invade Your Home: Understanding the Attraction

Fruit flies aren’t just randomly buzzing about; they’re meticulously drawn to specific conditions present within our homes. Understanding what attracts them is paramount to controlling and preventing infestations. The primary culprits are ripe and rotting fruit, fermentation processes, and overlooked food sources that often serve as breeding grounds. Let’s break down these attractants to understand how to make your home less appealing to these tiny invaders.

The Allure of Ripe and Rotting Fruit

The scent of ripening and, especially, decaying fruit is an irresistible beacon for fruit flies. These insects possess a highly developed sense of smell, allowing them to detect volatile organic compounds (VOCs) emitted by fruits from considerable distances.

As fruit ripens, it releases sugars and begins to ferment, producing alcohols and other compounds that fruit flies find incredibly attractive.

Overripe fruit, with its softened texture and heightened fermentation, becomes an ideal food source and breeding site. The female fruit fly lays her eggs on or near the surface of the fruit, providing a readily available food source for the larvae upon hatching. This is why a neglected fruit bowl can quickly transform into a fruit fly haven.

The Role of Fermentation

Fermentation is a critical attractant for fruit flies, playing a dual role as both a food source and an indicator of suitable breeding conditions.

Fermentation occurs when microorganisms, such as yeasts and bacteria, break down sugars into alcohol and other byproducts. This process releases a complex blend of VOCs that fruit flies are uniquely adapted to detect.

Beyond overripe fruit, fermentation can occur in a variety of unexpected places within the home. Spilled juice, improperly sealed jars of preserves, and even residue in empty beverage containers can provide sufficient fermenting material to attract fruit flies.

Areas like beer brewing equipment or wine-making supplies are especially prone to attracting fruit flies due to the concentrated fermentation processes.

Hidden Food Sources and Breeding Grounds

While fruit is the most obvious attractant, fruit flies are resourceful and can thrive on a variety of less conspicuous food sources and breeding grounds within the home. These overlooked areas are often the key to persistent infestations.

• Drains: Kitchen and bathroom drains can accumulate food scraps, grease, and other organic matter that ferment and provide a breeding site for fruit flies. The damp, dark environment within drains is also ideal for their development.
• Garbage Disposals: Similar to drains, garbage disposals often harbor decaying food particles that attract fruit flies. Incomplete grinding and infrequent cleaning can exacerbate the problem.
• Damp Areas: Damp mops, neglected sponges, and even the moist soil of houseplants can provide sufficient moisture and organic matter to support fruit fly populations.
• Empty Beverage Containers: Residue in beer cans, soda bottles, and juice cartons can ferment and attract fruit flies, even after the containers are seemingly empty.
• Spilled Food: Seemingly insignificant spills of sugary or alcoholic beverages, if left unattended, can quickly become a breeding ground. Pay special attention to areas under appliances, where spills may go unnoticed.

Identifying and eliminating these hidden food sources and breeding grounds is essential for long-term fruit fly control. A thorough cleaning regimen and a proactive approach to sanitation are crucial for preventing infestations and maintaining a fruit fly-free home.

Having learned about the fruit flies’ insatiable appetite for our kitchens’ sugary offerings, it’s time to consider the potential downsides of their presence beyond a mere nuisance. While seemingly harmless, these tiny insects can raise legitimate concerns regarding hygiene, food safety, and the overall well-being of our living spaces.

Concerns and Risks: Are Fruit Flies More Than Just Annoying?

Fruit flies are often dismissed as a minor inconvenience, but their presence can signify more significant issues. While not directly harmful like mosquitoes, they can contribute to unsanitary conditions, damage food, and generally create an unpleasant living environment. Let’s delve into the specific concerns and risks associated with fruit fly infestations.

The Annoyance Factor and Aesthetic Concerns

Perhaps the most immediately noticeable impact of a fruit fly infestation is the sheer annoyance they create. Their persistent buzzing and hovering around food and faces can be incredibly irritating, disrupting meals and daily activities.

Beyond the audible annoyance, their presence is aesthetically unappealing. Swarms of tiny flies detract from the cleanliness and hygiene of a space, leaving a negative impression on residents and guests alike. This can be especially problematic for businesses, such as restaurants and grocery stores, where a clean environment is paramount.

Potential for Contamination of Food and Surfaces

Fruit flies aren’t sterile creatures. They breed and feed on decaying matter, including rotting fruit, garbage, and even sewage. As they move from these unsanitary environments to our food preparation areas, they can carry bacteria and other pathogens on their bodies and legs.

This raises the possibility of contamination, where harmful microorganisms are transferred to food and surfaces. While the risk of serious illness is relatively low, it’s certainly not zero.

Consuming food contaminated with bacteria from fruit flies could potentially lead to mild gastrointestinal distress. Moreover, the simple thought of flies crawling over our food is enough to turn many people off their meal.

Health Implications: Spreading Bacteria

While fruit flies are not known to transmit diseases directly through bites or stings, their role in spreading bacteria is a valid concern. As mentioned above, they pick up microorganisms from unsanitary sources and deposit them on surfaces and food.

These microorganisms may include bacteria like E. coli and Salmonella, which can cause food poisoning. While the quantity of bacteria transferred by a few fruit flies is unlikely to cause severe illness in healthy individuals, it’s important to acknowledge the potential risk, especially for those with weakened immune systems, young children, and the elderly.

It’s crucial to maintain proper hygiene and food handling practices to minimize the risk of bacterial contamination from fruit flies and other sources.

Damage to Fruits and Other Food Items

Fruit flies are not only attracted to ripe and rotting fruit, but they also actively contribute to its further degradation. Female fruit flies lay their eggs on or near the surface of the fruit.

The larvae then burrow into the fruit as they feed, creating small holes and introducing bacteria and fungi. This process accelerates the spoilage of the fruit, rendering it unappetizing and potentially inedible.

Furthermore, fruit flies can infest other food items, such as vegetables, grains, and even sugary liquids. By laying eggs and introducing contaminants, they contribute to the overall degradation and waste of food resources. This can be particularly problematic for businesses dealing with large quantities of produce, leading to significant economic losses.

As we’ve seen, fruit flies can be more than just a nuisance; they pose potential risks to food safety and overall hygiene. Fortunately, numerous strategies exist to effectively control and eliminate these unwanted guests from our homes.

Eradication Strategies: Effective Methods for Getting Rid of Fruit Flies

Dealing with a fruit fly infestation requires a multi-pronged approach, focusing on both immediate elimination and long-term prevention. From simple DIY solutions to more intensive methods, understanding your options is key to regaining control of your living space.

Preventative Measures: The First Line of Defense

Prevention is always better than cure, and this holds true for fruit fly infestations. By implementing proactive measures, you can significantly reduce the likelihood of these pests making a home in your kitchen.

Proper food storage is paramount. Ripe fruits and vegetables should be stored in the refrigerator or in sealed containers to prevent fruit flies from accessing them.

Similarly, consistent sanitation is crucial. Wipe up spills immediately, especially sugary liquids and fruit juices, as these are prime attractants.

Regularly clean countertops, sinks, and garbage cans to eliminate potential food sources.

DIY Fruit Fly Traps: Simple Solutions with Household Items

For a light infestation, homemade traps can be surprisingly effective. These traps exploit the fruit flies’ attraction to sweet and fermenting substances.

One popular method involves placing a small dish of apple cider vinegar (or any vinegar) with a few drops of dish soap.

The vinegar attracts the flies, while the soap reduces the surface tension of the liquid, causing them to drown.

Another effective trap can be made using overripe fruit in a jar covered with plastic wrap. Poke small holes in the plastic wrap to allow the flies in, but make it difficult for them to escape.

Commercial Fruit Fly Traps: Convenience and Effectiveness

If DIY traps aren’t cutting it, commercial fruit fly traps offer a more convenient and often more effective solution. These traps typically utilize specialized attractants and designs to lure and capture the flies.

Sticky traps are a common option, coated with an adhesive that traps the flies upon contact.

Liquid traps contain a liquid attractant similar to DIY traps, but often with a more potent formula.

When choosing a commercial trap, consider its size, placement, and the type of attractant used to ensure it suits your specific needs and the severity of the infestation.

When to Consider Insecticides and Pesticides: A Last Resort

While generally discouraged due to potential health and environmental concerns, insecticides and pesticides may be considered as a last resort for severe infestations.

Aerosol insecticides can provide a quick knockdown of adult flies, but their effectiveness is limited and they don’t address the source of the infestation.

Residual sprays can be applied to surfaces where fruit flies are likely to land, providing longer-lasting control.

However, always exercise extreme caution when using insecticides and pesticides, carefully following the manufacturer’s instructions and wearing appropriate protective gear.

Ensure proper ventilation and avoid spraying near food preparation areas.

It’s important to prioritize other methods before resorting to chemical solutions.

Integrated Pest Management (IPM) Strategies: A Holistic Approach

Integrated Pest Management (IPM) offers a comprehensive and sustainable approach to fruit fly control. IPM focuses on preventing infestations through a combination of strategies, including:

• Monitoring for fruit fly activity to detect problems early.
• Identifying the source of the infestation.
• Implementing preventative measures like proper sanitation and food storage.
• Using traps and other non-chemical methods as the primary means of control.
• Only resorting to insecticides or pesticides when absolutely necessary and in a targeted manner.

IPM emphasizes long-term solutions and minimizes the reliance on harmful chemicals, promoting a healthier and more sustainable approach to pest control.

Home Pest Control Approaches: A Summary

Successfully eradicating fruit flies requires a combination of diligent cleaning, strategic trapping, and, when necessary, careful use of insecticides. By prioritizing preventative measures and employing a variety of control methods, you can effectively eliminate fruit flies and maintain a pest-free home. Home pest control approaches include:

1. Cleaning and Sanitation:
   • Regularly wipe up spills and crumbs.
   • Clean drains with boiling water and baking soda.
   • Keep garbage cans clean and tightly sealed.
2. Trapping Strategies:
   • Use DIY or commercial traps to capture adult flies.
   • Place traps near common breeding areas.
   • Monitor and replace traps regularly.
3. Insecticides and Pesticides (Use with Caution):
   • Only use as a last resort for severe infestations.
   • Follow manufacturer’s instructions carefully.
   • Prioritize safety and ventilation.

As we’ve seen, fruit flies can be more than just a nuisance; they pose potential risks to food safety and overall hygiene. Fortunately, numerous strategies exist to effectively control and eliminate these unwanted guests from our homes.

Preventing Future Infestations: Long-Term Solutions

Eradicating a fruit fly infestation is a victory, but preventing a recurrence is the ultimate goal. Sustaining a fruit-fly-free environment demands a proactive, long-term approach that extends beyond immediate extermination. This involves consistent effort in sanitation, diligent monitoring, and targeted cleaning to disrupt their breeding cycle.

Consistent Sanitation and Smart Food Storage

The cornerstone of long-term fruit fly prevention lies in strict sanitation. Fruit flies are drawn to decaying organic matter, making it essential to eliminate their food sources.

• Regularly clean countertops and surfaces, paying close attention to spills, especially sugary substances like juice and syrup.

• Wash dishes promptly; don’t leave them sitting in the sink overnight.

• Empty and clean garbage cans frequently, preferably daily, especially those containing food waste. Consider using trash cans with tight-fitting lids.

Proper food storage is equally critical.

• Refrigerate ripe fruits and vegetables to slow down the fermentation process that attracts fruit flies.

• Store dry goods in airtight containers to prevent access by any stray flies.

• Inspect fruits and vegetables for signs of damage or overripeness and discard them immediately.

By diligently practicing these habits, you significantly reduce the attractiveness of your home to fruit flies.

Diligent Monitoring: Catching Problems Early

Even with the best sanitation practices, fruit flies can occasionally find their way into your home. Regular monitoring allows for early detection and swift intervention, preventing a full-blown infestation.

• Keep a watchful eye for the appearance of even a few fruit flies, especially near fruit bowls, sinks, and garbage cans.

• Re-deploy DIY traps periodically as a proactive measure. Even if you don’t see any flies, the presence of a trap can act as an early warning system.

• Inspect incoming fruits and vegetables for any signs of fruit fly activity before bringing them inside.

Early detection provides the opportunity to implement control measures before the fruit fly population explodes.

Targeted Cleaning of Potential Breeding Grounds

Fruit flies don’t just feed on exposed food; they also breed in hidden, damp areas. Thoroughly cleaning potential breeding grounds is essential for long-term prevention.

• Clean drains regularly using a drain cleaner or a mixture of baking soda and vinegar, followed by hot water. This eliminates any build-up of organic matter where fruit flies can lay eggs.

• Clean garbage disposals by running them with ice and lemon or lime wedges to remove food debris.

• Check under appliances like refrigerators and dishwashers for spills or accumulated moisture. These areas can become breeding grounds if left unattended.

• Mop floors frequently, paying particular attention to areas under tables and around food preparation surfaces.

Addressing these often-overlooked breeding sites drastically reduces the fruit fly population and prevents future generations from taking hold.

So, next time you spot a blue fruit fly buzzing around your banana, don’t panic! Hopefully, now you’ve got a better idea of what they are and whether you should actually be worried. Keep an eye out, and happy fruit-snacking!
