a charipine wasp

Many thanks. There doesn't seem to be much of an ovipositor here. Would this wasp be a male or a female that deposits eggs beside, rather than inside prospective hosts? I gather from Graham Rotheray's book on Aphid Predators that parasitized aphids differ in colour, so I hope to look out for that.

Charipinae

the ovipositor is concealed when at rest, curled up inside the abdomen. Eggs are deposited inside the host. Yes aphids that have been attacked by aphidiine braconids are dry, swollen and usually a sort of dull golden colour. If you find these and rear them you will get braconids and all the hyprparasitoids including charipines
