Processionary Caterpillar Parasitic Fly - Carcelimyia dispa

Family Tachinidae

This page contains pictures and information about Processionary Caterpillar Parasitic Fly that we found in the Brisbane area, Queensland, Australia.
Body length 8mm
This medium size fly is grey in colour with short hairs covering the eyes. We found this fly a few times associated with the Processionary Caterpillars

The moths and caterpillars are protected by their dense long itch hairy and scale. The caterpillars are further protected by their silk bag shelter and habits. They do not have many predators. However, scientists do found that they are subjected to parasite by Tachinid Fly.

Scientists found the pupa cases of Tachinid Fly inside their bag-shelter. From reference information, Processionary Caterpillars is parasite by the Tachinid Fly Carcelimyia dispar (Diptera: Tachinidae: Goniinae).

We took the photos in this page when observing the Processionary Caterpillars. There was the Tachinid Fly very interested and watching the small caterpillars. It is believed that the Tachinid Fly lays eggs on leaves and those eggs which enters the caterpillars body while they are feeding
When observing the caterpillar bag-shelter, we also saw saw those Tachinid Fly.

Processionary Caterpillar Parasite

On May 2009, we collected some matured Processionary Caterpillars. We put them in a small tank. Inside we put a thick layer of sand covered with plant materials. Those caterpillars hide under the plant materials. Nothing happen for a long time.
