My books say this is a Lucilia. But the colour is more like Cynomya. Who can help?
The fly on the picture measures 10-11 mm., and was caught on 15.VII.2005.

The behavour was different from that of the Lucilia I know. Last june and july about 2-5 flies were present between the hundreds of Calliphora's around our house on the Dutch Waddensea Island of Griend. There was also some interaction, the flies on the picture jumping on Calliphora every now and then.
