Tachinid fly - Subfamily Dexiinae
- This page contains pictures and information about Tachinid
Flies subfamily Dexiinae (or Proseninae in some
reference) that we found in the Brisbane area, Queensland, Australia.
- This is a very large subfamily. The Dexiinae mostly are parasitic in larval Coleoptera
(beetle) especially Scarabaeidae.
How do they locate their host is remain unknown. Larvae develop in the host
and pupate either within its remains or in the surrounding.
are usually found resting on tree trunk. Usually they have long legs, with
face elongated under eyes.
- Flies in subfamily Dexiinae have the following characteristic;
- - typical dexiin face with facial carina and board gena
- - excavation of abdomen T1+2 reach to hind margin,
- - eyes bare
- - no reclinate orbital setae
- - row of frontal setae down to lunula only
- - scutellum with three pair of marginal setae
- There are two tribes, Dexiini and Rutiliini, in this subfamily Dexiinae.
