Bee Fly
Bombyliidae family
Bee Flies (family Bombyliidae) are a fascinating and diverse group of native Australian flies that are often mistaken for bees due to their stout, furry bodies and hovering flight. It is essential to recognise that Bee Flies are not pests. They are, in fact, highly beneficial insects that play two important roles in the ecosystem. As adults, they are avid nectar-feeders and are important pollinators of many native plants and some agricultural crops. As larvae, most species are parasitoids, meaning they develop by feeding on the larvae of other insects, such as beetles, grasshoppers, and other flies, helping to control their populations naturally. This guide is designed to prevent the misidentification and unnecessary harm of these valuable garden visitors. Information on 'control' is focused on clarifying that none is needed, while 'prevention' is reframed as how to encourage their presence in your garden.
For effective control and prevention, professional pest management is recommended.

Identification
How to accurately identify Bee Fly
Expert Tips
Professional pest controllers recommend examining Bee Fly under good lighting conditions, focusing on Key features are the combination of a furry, bee-like body, large eyes, a long and rigid proboscis (in many species), and the ability to hover in mid-air like a hummingbird. Their wings are often held out at a 'V' angle when resting.. Specimens are best observed during their peak activity periods and in their preferred microhabitats. Digital photography with macro capabilities can aid in confirming identification markers for consultation with entomological specialists.
Similar Species
- Bees (Apis, Lasioglossum etc.): Bees have four wings (though they are hooked together to look like two), thicker antennae, and can sting. Bee flies have only two wings and cannot sting.
- Hoverflies (Syrphidae): Another family of bee-mimicking flies. Hoverflies are often less hairy and many have flatter abdomens with bright yellow and black patterns. They typically do not have the long, rigid proboscis of a Bee Fly.
- Native Wasps: Wasps are generally less hairy, have a distinct narrow 'waist', and can sting.
Confusion Species
Bee Fly is most commonly confused with similar pest species in the same ecological niche. Key distinguishing features include the specific pattern of Colour is extremely variable. Many species are brown, black, or grey, often with patterns of yellow, white, or orange hairs that mimic the patterns of bees or wasps. Some are brilliantly metallic. and Key features are the combination of a furry, bee-like body, large eyes, a long and rigid proboscis (in many species), and the ability to hover in mid-air like a hummingbird. Their wings are often held out at a 'V' angle when resting.. Professional identification often requires examination under magnification to confirm diagnostic features. When in doubt, collect specimens for expert identification, as accurate species identification is crucial for effective pest management strategies in Australian conditions.
Identification Tips
If you see a furry insect hovering like a tiny helicopter in front of a flower, and it has a long, needle-like 'beak' for drinking, it is almost certainly a Bee Fly. Watch its wings when it rests; a fly has only one pair. Its agile, darting and hovering flight is also very characteristic. Remember, they are harmless friends of the garden.
Identification Tools
Simple observation of their hovering flight and long proboscis is usually enough. A camera can help capture their features for a closer look.
Photographic Evidence
A photo of the fly hovering near a flower, showing its proboscis and furry body, is excellent for identification.
Key Identifying Features
- A furry, stout body, often mimicking the appearance of a bee.
- The ability to hover motionless in mid-air, often with a high-pitched hum.
- A long, slender, forward-pointing proboscis used for sipping nectar.
- Large compound eyes that cover most of the head.
- They are completely harmless and cannot bite or sting.
Common Misidentifications
Most commonly misidentified as a native bee or a honeybee. This can cause people to fear them unnecessarily. The key difference is that Bee Flies cannot sting.
Key Identification Features
The Bee Fly (Bombyliidae family) can be reliably identified through several diagnostic characteristics. Size: Bee Fly measures A highly diverse family, with species ranging from small (3mm) to very large (20mm).. Coloration: Colour is extremely variable. Many species are brown, black, or grey, often with patterns of yellow, white, or orange hairs that mimic the patterns of. Key features: Key features are the combination of a furry, bee-like body, large eyes, a long and rigid proboscis (in many species), and the ability to hover in mid-air like a hummingbird. Their wings are often held. Structure: The body is stout and often very hairy. The most notable feature for many species is the long, slender proboscis that projects forward from the head, . These identification markers are consistent across Australian populations and are critical for accurate field identification by pest control professionals and property owners.
Professional Identification
Not required. They are easily recognisable and are not a pest, so no professional intervention is ever needed.
Biology & Lifecycle
Understanding Bee Fly biology and development
Anatomy
Bee Fly (Bombyliidae family) exhibits typical flies anatomy with specialized adaptations. The body is stout and often very hairy. The most notable feature for many species is the long, slender proboscis that projects forward from the head, used for sipping nectar deep within flowers.. In many species, the eyes of the male meet at the top of the head (holoptic), while the eyes of the female are separated (dichoptic).. These anatomical features are optimized for their ecological role and contribute to their success in Australian environments.
Genetics
Genetic studies of Bee Fly populations reveal Females lay a large number of eggs, as the chances of any single egg successfully reaching a host are very low. that contribute to population dynamics. Genetic diversity within Australian populations influences their adaptability to local environmental conditions and pest management resistance development.
Lifecycle Details
Egg Stage
The egg-laying strategy is remarkable. The female Bee Fly often hovers and flicks her eggs with great precision towards the burrow or vicinity of a suitable host insect, such as a ground-nesting bee or a beetle grub in the soil. Some species coat their eggs in sand or dust for camouflage and weight before flicking them.
Adult Stage
The adult Bee Fly emerges from the pupa, leaving the remains of its host behind. The adult stage is the conspicuous, flying stage. Adults are sun-loving and spend their days visiting flowers to feed on nectar and search for mates. The adult lifespan is typically a few weeks.
Pupal Stage
Pupation occurs within the host's burrow, nest, or pupal case. The pupa is often equipped with spines and bristles which it uses to push its way to the surface of the soil just before the adult emerges.
Larval Stage
The first-stage larva, called a planidium, is tiny, mobile, and actively seeks out the host. Once it finds the host (e.g., a beetle larva or a wasp nest), it attaches itself and begins to feed. In later moults, the larva becomes a more sedentary, grub-like parasitoid, consuming the host from the inside or outside. This stage is hidden from view and is the primary feeding stage of the fly's life.
Seasonal Cycle
Adult Bee Flies are most commonly seen in spring and summer when flowers are abundant. The larval and pupal stages overwinter in the host's environment.
Development Time
The development time from egg to adult is highly variable and can take anywhere from a few months to over a year, depending on the species and the development time of its host.
Reproduction Rate
Females lay a large number of eggs, as the chances of any single egg successfully reaching a host are very low.
Generations Per Year
Most species likely have one generation per year, with their lifecycle timed to coincide with the lifecycle of their specific host insect.
Maximum Temperature
They are sun-lovers but may seek shade during the absolute peak of summer heat.
Minimum Temperature
They are inactive in cold or overcast weather.
Optimal Temperature
Adults are active during warm, sunny weather, which is ideal for flight and nectar feeding.
Environmental Factors
The presence of both suitable flowering plants (for the adults) and suitable host insects (for the larvae) are the critical environmental factors for their survival.

Frequently Asked Questions
Common questions about Bee Fly
Does the Bee Fly sting or bite?
No, absolutely not. Despite its convincing resemblance to a bee, the Bee Fly is completely harmless. It is a true fly, belonging to the order Diptera, which means it only has two wings. It does not possess a sting like a bee or wasp. Furthermore, its mouthpart, the long proboscis, is designed like a rigid straw for sipping nectar deep within flowers. It is physically incapable of piercing skin to bite. You can observe and appreciate these fascinating creatures in your garden with complete confidence that they pose no threat to you, your children, or your pets. Their bee-like appearance is purely a clever defensive mimicry to fool predators.
I saw a Bee Fly. Does this mean I have a pest problem?
Quite the opposite! Seeing Bee Flies in your garden is a positive indicator of a healthy and balanced ecosystem. It means you have a 'good bug', not a pest problem. Their presence indicates two wonderful things about your garden. Firstly, you have enough flowering plants to provide a food source (nectar) for the adult flies. Secondly, and perhaps more importantly, your garden supports a variety of other insects that the Bee Fly larvae can use as hosts. Since many of these host insects are beetles and grasshoppers, the Bee Fly is actively helping to control potential garden pests for you, free of charge. You should view them as a welcome visitor and a sign that your garden is thriving.
What is the difference between a Bee Fly and a regular bee?
While they look similar, there are a few easy ways to tell them apart. First, count the wings: Bee Flies, like all flies, have only **one pair (two wings)**. Bees have **two pairs (four wings)**, although the front and back wings are often hooked together and can be hard to see separately. Second, look at the eyes: Bee Flies have very large eyes that often dominate their whole head. Third, check the antennae: Bee Flies have very short, often inconspicuous antennae, whereas bees have longer, more noticeable antennae. Finally, watch their behaviour: Bee Flies are masters of hovering, able to hang perfectly still in the air like a tiny helicopter, which is a flight pattern less common among bees. And remember, the Bee Fly cannot sting.
How do Bee Flies help my garden?
Bee Flies provide two fantastic, free services for your garden. The first is **pollination**. As the adult flies move from flower to flower drinking nectar, they transfer pollen, helping your plants to produce fruit and seeds. They are important pollinators for many native Australian plants. The second service is **natural pest control**. The larvae of Bee Flies are parasitoids. The female fly lays her eggs near the larvae or eggs of other insects like grasshoppers, beetles, and solitary wasps. The Bee Fly larva then hatches and feeds on the host insect, killing it in the process. By doing this, they help to keep the populations of these other insects, some of which can be garden pests, in check. They are a valuable part of an integrated pest management strategy.
How can I attract more Bee Flies to my garden?
Attracting Bee Flies is a great way to boost the health of your garden. The best way to do this is to plant a wide variety of flowering plants, particularly native species. They are especially attracted to plants with lots of small flowers, like daisies, or plants with tubular flowers that suit their long mouthparts, such as grevilleas or correas. Planting flowers that bloom at different times throughout spring and summer will provide a continuous food source for them. The second crucial step is to **avoid using broad-spectrum chemical pesticides**. These chemicals are indiscriminate and will kill beneficial insects like Bee Flies just as easily as they kill pests. By creating a flower-rich, pesticide-free environment, you will make your garden a welcoming haven for these helpful and beautiful pollinators.
