Tephritid Flies

A pair of Tephritid flies, probably Chaetostomella cylindrica (Diptera: Tephritidae), mating on knapweed (Centaurea sp).

The following photo shows a male with everted pheromone sacs on the sides of the abdomen.  These sacs release a pheromone that attracts females.

Photos taken in Whiteknights Park, Reading, UK, on 2013-05-27 (first photo) and 2013-05-25 (second).
