Tachinid fly - Family Tachinidae

This page contains pictures and information about Tachinid Flies that we found in the Brisbane area, Queensland, Australia.
 
Tachinid fly - this fly parasites in moth caterpillar

All Tachinid Flies share the parasitoid habit, their larvae are parasites in other insects. They mainly parasites on larvae of moths or butterflies, larvae or adults of beetles, adults of bugs, or adults of various orthopteroid orders, such as grasshoppers and stick insects.

Tachinidae is one of the largest families of Diptera. Tachinid flies are relatively soft bodied, from small to large size insects. They may be drab, brightly coloured, or mimics wasp. Tachinid flies are extremely diverse in appearance and many do not have the typical grey-black, bristly faces.

The larvae are known as maggots and often are worm-like lacking appendages. They are usually adapted to live in their food. Adult flies can be found in almost all habitats resting on foliage, feeding at flowers or, in the case of females, flying quietly in search of hosts. Males may be seen resting on larger tree trunks.

We found quite a number of different species of  Tachinid Flies. Most of them look similar and hard to be identified. However, we are quite sure they belong to this family. There are five subfamilies recorded from Australia. We found species in four and listed as follows;
 

Phasiinae

This subfamily parasitic in Hemiptera. Their abdomen is bare of bristles and is either globular or quite flat and round.
 
We did not capture any photos of them yet.  

Dexiinae 

The Dexiinae mostly are parasitic in larval Coleoptera (beetle). Adults are usually found resting on tree trunk. Usually they have long legs, with face elongated under the eyes.
 

Tachininae

The Tachininae are mostly parasitic in Lepidoptera (moth and butterfly). Most of the are very bristly.
 

Goniinae

The Goniinae are mostly parasitic in Lepidoptera (moth and butterfly).
