 This fly, I found yesterday on Cirsium vulgare in my garden in Dortmund West Germany.

Which fly is it? And what are the two "things" at the back?

 Eversible pleural sacs? These apparently may be for sensory or courtship purposes? http://www.diptera.info/forum/viewthread.php?thread_id=25094&pid=111665#post_111665

I have just received the very sad news that Peter Chandler has died after a fall at home yesterday. I have no other details at the moment. We shall miss him terribly.

I will try to fix the messages this month. We have to make some other configuration changes before software goes out of support at end of year.
