Orchid Dupe Wasp 


Subfamily Pimplinae - Banded-abdomen Ichneumon Wasps

Order Hymenoptera, Family Ichneumonidae

This page contains pictures and information about Banded-abdomen Ichneumon Wasps in subfamily Pimplinae that we found in the Brisbane area, Queensland, Australia.
Ichneumon Wasps in subfamily Pimplinae are usually coloured with red, yellow or black colours. They are from small to very large in size. Pimplines attack a wide range of insect larvae and pupae, and some attacks spider egg sacs. Prior to laying eggs, the female wasps often paralyse or kill their host by injecting venom with the ovipositor.

This is quite a large Ichneumon wasp. We found the male and female flying on vegetations in someone's front yard during a sunny day in mid winter. They both have the typical wasp colour pattern and with very long antenna. Notice the female have the long and strong ovipositor at the tip of her abdomen.

Sericopimpla australis or S. crenator, tribe Ephialtini, body length 20mm
In early spring we found this Ichneumon Wasp attacking a case moth caterpillar on a Acacia tree. Although the caterpillar was protected by its case bag, it seemed it was useless to prevent the attack from the wasp. We saw the caterpillar head come out a few times try to get rid of the wasp but no use either. The wasp kept punching with her long ovipositor into the case bag for over half an hour.
