A great day in Cholsey

Tony’s meadow in Cholsey has been a survey site for the Hornet Robberfly (Asilus crabroniformis) because it is the center of a thriving population and he has been monitoring them himself for many years.

Today I went over there with my friend Carim, who had traveled out from London specially to see Asilus. The weather was a bit overcast but there were still plenty of Asilus in the meadow (Tony saw 27 on a transect) and I photographed quite a few tachinids on the Wild Carrot.

The rest of the flies are all tachinids – mostly fairly common summer species but it was nice to find Bithia spreta in Tony’s meadow for the third successive year.
