Apparently ovipositing on a beetle larva which has a fecal pellet shield. Photographed on a thistle in a field near Reading, UK, 2011-05-25.

Sould be Dufouria chalybeata, a parasitoid of Cassida spp. (Chrysomelidae).

Wow - excellent photos - well done! :) Yes, Dufouria chalybeata are fairly common at the moment in our area and are small, black and mainly shiny :)

Ah, another Dufouria. I had one of them a few days earlier. This one seemed very excited but, whenever I disturbed it, it always came back to the same spot. It was only later that I noticed the larva in the photos. Being on a thistle I presume the larva was probably that of the thistle tortoise beetle, Cassida rubiginosa.
