Case Moth Larvae Parasite Wasp - Sericopimpla australis or S. crenator
Family ICHNEUMONIDAE
This page contains pictures and information about Case Moth Larvae Parasite Wasps that we found in the Brisbane area, Queensland, Australia.
- 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 the bag was not effective to prevent the caterpillar from attacked by the wasp. We saw the caterpillar head come out a few times trying to get rid of the wasp but not effective either. The wasp kept punching with her long ovipositor into the case bag for over half an hour.
- Sericopimpla sp. Parasite Wasps sting case moth larvae to death then lay an egg attached to the inside of the bag. The egg hatches in a few days and larva feeds externally.
- This ichneumon wasp species could be the Sericopimpla australis or S. crenator in subfamily Pimplinae. Please check the Ichneumon Wasps page for general information about this wasp.
