I have been rearing a caterpillar of the Dun-bar (Cosmia trapezina) found on Beech at Hawksworth wood on 14th May 2011.
Yesterday, I looked inside its container to find that the caterpillar's innards are now contained within the pupa of an ichneumon wasp. Mark Shaw has since identified this for me as Scirtetes robustus.
It will be fascinating to see what the resultant parasitoid imago looks like.
