A brachypterous male Oligosita sp wasp of the Trichogrammatidae found at Great Dixter.
Every year several of these brachypters are found and it is impossible to determine species. Would be good to sequence the DNA in order to work out exactly what they are.

View looking directly at the head and antennae of a tiny wasp. This is a slide mounted image. The circular brown part is the head, with large black eyes either side.
