Black Flower Wasp 1 - Epactiothynnus  sp.

FAMILY TIPHIIDAE

This page contains pictures and information about Black Flower Wasps that we found in the Brisbane area, Queensland, Australia.

Two winged males body length 20mm
 
This Flower wasp is black in colour with yellow spot pattern on thorax. The pattern vary among individuals. As all other Flower Wasps, female is wingless. The female legs are modified for digging and her wings are lost. We sometimes found this wasp on sandy footpath in Karawatha Forest and other Eucalypt forest in Brisbane.

It is common to see a male Flower Wasp carrying a wingless female, with tail to tail attached, flying between flowers. 
 

Two Males Fighting 

On Jan 2009 in Brisbane Koala Bushlands near Burbank, we saw two male flower wasps looking for something on the sandy forest floor. We believed they sensed the smell of female flower wasp.

When the two males met with each other, there was the fighting. It was only a light combat, took a few second,  then the two wasps separated and kept searching again. When they met they start the small fight again......and again.......
