This page contains pictures and information about Spine-legged Robber Flies in Subfamily Dasypogoninae
that we found
in the Brisbane area, Queensland, Australia.
- Robber flies in this subfamily have the wing vein R2+3 open, ending on the
wing margin. Their antenna terminal is sometimes thickened. The fore tibia
with an apical spur; one of the spines at the apex of the ventral side of the
fore tibia is enlarged.
- The Dasypogoninae subfamily used to be a larger group. Those robber fly species
were recognised within this group by the large spine on the front tibiae. This has been used as a diagnostic character for Dasypogoninae. Based on the phylogenetic hypothesis derived by Dikow (2009) this spine has been independently derived at least once in the Australian
Brachyrhopalinae. They are transferred to the newly erected Brachyrhopalinae.
- Robber Flies in Subfamily Dasypogoninae can be recognized by the following
- - antenna terminal is sometimes thickened,
- - with apical spur on fore tibiae,
- Spider-wasp-mimicking Robber Fly
- ? Apothechyla sp., body length 20mm
- This Robber fly has a black body, very long legs and golden wings. Its
colour pattern mimics the Spider
Wasp. It was resting on a large tree trunk in Karawatha Forest during early
summer. When we came close, it opened it wings, bend its abdomen , making the
stinging action and show its yellow bands on its abdomen, tried very hard to
convince us that it was a real Spider wasp.
