Hello

Is it possible to confirm the ID of this fly found yesterday in a calcareous grassland ?
Basicosta are whitish, each mid tibia has 2 ad. Is the frons narrow enough to exclure species as L. regalis ?
This fly is much smaller than the usual Lucilia sericata that I find on flowers.

The keys by Mihalyi (http://publicatio...69_181.pdf) and Rognes (https://www.resea..._in_Norway) give a detailed description of shape and distribution of setae and hairs on the tergites, which in your picture, to me, match L. richardsi. Being no Calliphoridae expert, that's all I can say...
Regards, Sundew

Thank you Sundew. I used Mihalyi's key but I didn't know Rognes's publication that is more precise about setae on abdomen and frons width. Indeed, it looks good for richardsi. To be confirmed...

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
