Hello!

This fly (from yesterday, Ostwestfalen/Germany) was almost as large as one of the many Calliphora females flying around at the moment. But it had no blue color. What could it be? The only possibility, which comes into my mind, is a big, rather worn Pollenia. That genus was also numerous in the last days, but they are mostly 7-8 mm long and much more slender like this typical one:

Hi J?rgen
This is indeed a Pollenia - the wavy golden hairs are visible on the sides of the thorax. Don't worry about the size differences - they can vary quite a bit - depends on the size of the host and the number of larvae parasitising it.

Thanks a lot, Tony! It was not only the mere size, which irritated me, also the "fat" shape Wink.
