FAMILY POMPILIDAE - Spider Wasps
This page contains pictures and information about Spider Wasps that we found in the Brisbane area, Queensland, Australia.
Most member in this family are large wasps. All of them are solitary insect. The female mates and then prepares nests (usually on ground in soil) and food for her young. The male has shorter life span and die shortly after mating. The egg hatches and the larva feeds on the supplied food, usually spiders. After pupation the new adults emerge, seek a mate and restart their life cycle.
Most of the Spider Warps are orange and black, black and grey/white markings or just black, i.e., the very strong warning colours. They usually have tinted wings, smooth and shiny body. Their hind-legs are long and always have two prominent spurs. They tend to coil their antennae. They usually hunting on ground with the characteristic wing flicking movement.
Females have very powerful sting. They hunt for spider, which they grasp and sting. The spider is then paralyzed and dragged back to nest and lay egg on it. The egg hatches and will feed on the spider.
Females provision cell of nest with a single paralysed spider. So Spider Wasps attacked spiders with about the same size or even slightly bigger, although they are rarely prey-specific. Some Spider Wasp species mostly hunt for spiders on ground and a few specially hunt for web building spiders.
In a sunny summer day, we sometimes see Spider Warps walking, hopping and flying short distance between plants near the ground, with wings flicking rapidly. They are hunting for spiders as the food for their young.
Pepsinae
- Orange Spider Wasp 1
- Priocnemis bicolor, subfamily Pepsinae, body length 30mm
- This wasp is large. Its head, legs and antenna are in orange colour, thorax and eyes are in black colour. Its wings are in orange colour with black tips. More information and pictures can be found in this page.
- Orange Spider Wasp 2
- Cryptocheilus bicolor, subfamily Pepsinae, body length 30mm
- This wasp is large. Its head, legs and antenna are black and orange-yellow in colour, thorax and eyes are in dark brown to black colour. Its wings are tinted in orange brown colour. There are the broad orange bands on its black abdomen. We have some observations and recorded in this page.
- Yellow Antenna Black Spider Wasp 1
- Fabriogenia sp., subfamily Pepsinae, body length 20mm
- We sometimes see this black wasp searching prey on gum tree bark. The wasp has the long bright yellow antenna. More information and pictures please visit this page.
- Yellow Antenna Black Spider Wasp 2
- Fabriogenia sp., subfamily Pepsinae, body length 20mm
- This black wasp looked similar to the one above but has the dark wings instead of banded wings. We believed they are different species. Please check this page for more information.
- Mud Nest Tenant Wasp
- ? Auplopus sp., subfamily Pepsinae, length 20mm
- This wasp look similar to the common Common Mud-Dauber Wasp except with yellow pattern on top of its thorax. However, it is wandering on the mud nest but not building the nest. If the wasp was not building the nest then it could be a parasite wasp. This is a very interesting story. Please keep reading at this page.
Pompilinae
- Zebra Spider Wasp
- Turneromyia or Ctenostegus sp. subfamily Pompilinae, body length 20mm
- We saw this wasp once in Karawatha Forest during early summer. It was searching on the forest floor. We have more pictures and information in this page.
- Orange-thorax Spider Wasp
- Turneromyia or Ferreola sp. subfamily Pompilinae, body length 20mm
- This wasp is medium size, black in colour with black tinted wings and orange-yellow thorax. It was hunting on trees and grasses with wing and antenna flicking movement, the special characteristic of spider wasp. Also notice the two prominent spurs on the legs. We saw this wasp once in Daisy Hills near Buhot creek on Dec 2009. Please check this page for more information.
