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! Smile Yes, Dufouria chalybeata are fairly common at the moment in our area and are small, black and mainly shiny Smile

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.

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
