Bee Flies - Family Bombyliidae
This page contains pictures and information about Bee Flies that we found in
the Brisbane area, Queensland, Australia.
Bee Fly adults have long proboscis and feed on nectar and pollen. On a sunny
day, they are
often seen on feed on flowers, hovering over vegetation or rest on bare ground.
They are the the import pollinators, some are even the primary pollinators of
some species of flower plants.
Bee Flies are hairy, most of them mimic wasps or bees (Batesian
mimics of Hymenoptera). However, they have stout and woolly body and do not have narrowed waist. Their wings are easily recognized with
distinctive vein pattern, usually dark in colour,
some with patterns or spots. When at rest, their wings are flat in outspread
position. Their head is occupied by their large eyes, more or less in
hemispherical shape. Their legs are slender and without bristles. Their claws
are small.
Bee Flies favour warm, and sunny localities. Most have a strong, hovering
flight and are usually found hovering on blossom or patches of bare soil.

Mimic wasp
Most of their larvae are parasitic on other insects' eggs or larvae. Very
few others are predaceous, free living in soil. As you might imagine, their larvae
are hard to be found.
Both flies in Bee Flies family and Hover
flies (Syrphidae) family mimic bees. The main
character to recognize between them is Bee Flies have longer wings. Hover Flies
have shorter wings with a series of closed cell on the wings hind
margins.
-
- Bee Flies in the subfamily usually have the slender body covered with
short hairs. They also have long and slender proboscis to feed on
flowers.
-
- Bee Flies in the subfamily
Bombyliinae usually have the stout and hairy body, with
long and slender proboscis. The wing vein M1 meets R5 before the wing
margin. Sometimes this subfamily is called True Bee Flies because their
hairy body resembles bee.
-

- In this subfamily, the Bee flies have relatively longer wings and longer
body. Their wing vein Rs forks well before r-m, with R4 and R5 strongly
looped. They usually have the narrower and flattened abdomen.
-
- Anthracinae is a very large subfamily. We found quite a number of
species in this subfamily and listed in different tribes as below;
- Bee Flies in this tribe have their wing vein Rs forks very close
to cross vein r-m. They are close to the Exoprosopini except
they have a pencil of hairs at the tip of antenna. They are from small to
medium in size. Most of them are dark brown to black in colour, with
patterned wings.

- In this tribe, the Bee flies also have their wing vein Rs forks very close
to cross vein r-m. They have stout body comparing with Bee Flies in
other groups.
