Metallic Brown Spider Wasp


FAMILY SCOLIIDAE - Hairy Flower Wasps

Order Hymenoptera

This page contains pictures and information about Hairy Flower Wasps in family Scoliidae that we found in the Brisbane area, Queensland, Australia. 
Most members in this family are large wasps. All of them are solitary wasps, both male and female are winged. They are mostly yellow, orange or black. 
The larvae are ectoparasitoids of the grubs of beetles, usually Scarab Beetles, but rarely Weevils. The females burrow extensively in the soil to locate host grubs. They seems to often utilize the burrows made by the grubs themselves. The females then paralyze the grub and lay eggs on it. Pupation occurs within the cell occupied by the host. Adults feed on flowers.
All Australian species are in subfamily Scoliinae.

This Blue Flower wasp is shiny dark blue in colour. Its wings are tinted in dark blue colour as well. When flying under sunlight, it reflect the bright blue light. We sometime see them flying and walking among shrubs searching for prey. Please check this page for more information.

Campsomeris tasmaniensis, male, body length 30mm
There were a number (more than 10 at a time) of Hairy Flower Wasps flying around in our backyard from May to June 2007. They were flying very close on the lawn and following a circular figure 8 course. We suspected that there could be the females emerging from the ground and the males just waiting for the mating chance there. Detail story can be found in this page.
