Tachinid fly - Subfamily Tachininae

This page contains pictures and information about Tachinid Flies Subfamily Tachininae that we found in the Brisbane area, Queensland, Australia.
 
The Tachininae are mostly parasitic in Lepidoptera (moth and butterfly). Most of the are very bristly.

Phorocera sp., body length 8-10mm
There are pictures of different Tachinid flies with grey hairy body in this page. Thy are 10-12mm in body length. They look similar but quite likely are different species. When we raised moth and butterfly caterpillars, there are quite often come out those flies instead of moths/butterflies.

Microtropesa sinuata, body length 15mm.
This is a very fat Tachinid fly. The abdomen is dark shiny blue background colour. The thorax is shiny brown background colour. Both abdomen and thorax have a lot of brightly white triangular spots. It has a pair of big red eyes on the orange head. Its antenna is distinctive too, orange with black tips. We found it when it was feeding on flowers of Lantana plants.

? sp., body length 10mm.
This fly was checking a group of sawfly larvae. The fly has the grey thorax and brownish-yellow abdomen. The 2nd picture show a Tachinid Fly checking the Leaf Beetle Larvae and about to lay eggs on the larvae. The white eggs of the fly are attached on the body of the larva. The egg hatches into maggot and bores into the body of the Leaf Beetle larva, develops inside and kill the larva. Please check this page for more information.
