Hello! This fly was sunbathing on a tree trunk yesterday (Ostwestfalen/Germany). It was a little bit bigger and more slender than Lucilia. I suppose it could be Gymnocheta viridis, right? Thanks in advance!

Juergen, Congratulations, that's the one. Males are typically found on stems or trunks of trees in the sun. Well illustrated by your picture Theo Zeegers |

Hello, Chris! Chris Raper wrote: Yup G.viridis were out in force yesterday in Oxfordshire, England. Two days ago, when that photo was taken, it was the only individual. Yesterday (22 ?C) there were dozens of them on many trees at the wood :-).

Yes, they can be very numerous. Reminds me of the time I ran a Malaise trap next to a G.viridis tree. When I set the trap there were 4-5 flies on the tree - when I collected the trap 3 days later there were about 10 flies in the trap and 4-5 on the tree. This pattern went on for 2 weeks - I always caught plenty but there were always 4-5 more on the tree. Needless to say, I wasn't trapping for G.viridis - they were just unfortunate to be in my trapping area. The population wasn't affected in subsequent years - i just think flies are less territorial and far more mobile in the countryside than most people think. |
