Species Biology


  • 6-10mm

  • Iridescent red abdomen
  • Abdomen tip with four sharply-defined teeth
  • Separation from other Chrysis is difficult. The use of a microscope and specialist keys are required for identification.


Poorly known in Ireland. It has been found in a variety of habitats including woodland, gardens, stone walls, heathland and coastal areas. 

Flight period

It has been recorded from May-July in Ireland. In Britain it can fly until September.

Nesting biology

A kleptoparasite. The female will enter the nest of other solitary species (in this case member of the genus Ancistrocerus) and lay an egg. The egg will hatch and the larvae will consume the egg of the host species before feeding on the small caterpillars deposited by the female host wasp. In Ireland the  host species appears to be the Small-notched Mason Wasp (Ancistrocerus gazella), although other hosts may also be used. 

Flowers visited

Not an avid nectar feeder, but it will occasionally visit composite flowers such as Hogweed (Heracleum sphondylium) or Yarrow (Achillea millefolium).

Native region

Europe, North America, Temperate Asia
