Hover Fly Larvae Parasite
Wasp - Diplazon laetatorius
This page contains pictures and information about Hover Fly Larvae Parasite Wasps
we found in the Brisbane area, Queensland, Australia.
- Body length 10mm
- The Hover Fly Larvae Parasite Wasp is in family ICHNEUMONIDAE and also called Ichneumon
Wasp. This wasp lay eggs on Hover Fly
larvae. The Hover Fly larvae feed on aphids.
The wasp is shiny black in colour with brown legs and brown abdomen. There is
the white segment on their hind legs.
- Hover Fly larvae, length
Pupa, length 10mm
- We found the larvae amongst feeding on the aphids and we thought it was a Hover Fly larvae
although it was darker in colour and 1-2 mm longer. A few days later it turn
into a pupa and look like a Hover Fly pupa too. However, a week later, it emerged
as a Ichneumon Wasp.
- We then thought there are two different larvae which look the same
and both feed on aphids.
- The wasp just emerges from pupa. It fly away after its wings is dry and
- A few weeks later, on a milkweed plant, where is a lot of aphids, we
find two larvae. The two larvae look exactly the same. They turned into two
pupa look exactly the same. However, one emerged a hover fly and a
few days later one emerged a wasp. We started to suspect they were all hover fly
larvae but one parasited by Ichneumon
