Order Hymenoptera
- This page contains pictures and information about the Hatchet Wasps in Family
Evaniidae that we found in the Brisbane area, Queensland, Australia. They
are also known as Ensign Wasps.
-
- The Hatchet Wasps have the flat and short abdomen which look like a hatchet.
The
"hatchet" moves up and down when the wasp walks. They are mostly
black in colours. Antenna is 13-segmented. They rest with fore wings fold
longitudinally.
-
-
-
- They are solitary wasps parasitic on cockroach
oothecae. They are usually found searching hosts on tree trunk, leaf
litter and in buildings.
