Life History

In Britain this wasp is a parasitoid of Buff and White Ermine moths. The female injects her long ovipositor inside the host caterpillar and deposits her eggs into the caterpillar’s body. Her young hatch and devour their host, pupate, and emerge to begin the cycle again.

UK Status

Not well recorded in Britain where it appears to be widespread but uncommon.

VC55 Status

It appears to be uncommon in Leicestershire and Rutland. We believe the Sapcote record of 7th September 2015 is the first for VC55.
