Hello, an 8-9 mm Muscidae at some fruits in our courtyard this afternoon (northwest Germany). At first I thought of the usual Phaonia tuguriorum, but on a closer look I am not sure anymore...

Sorry, one more question: could this one from today at a cut log at the forest border be the same species?

Hi Jürgen, very likely, the only thing that contradicts: Gregor et al state that the should appear IV to IX. But I've found them in XI, too...
Greetings, Eric |

Thanks again, Eric! I think, most of the flies that overwinter as adults, become temporarily active on warm and sunny winter days. I found Neomiya cornicina, Scathophaga stercoraria and Calliphora vicina today, too (and even at the beginning of January, when it was 16 °C warm).

Here in Reading, UK I have foiund Phaonia trimaculata is actually most common in the winter months. The plot below is based on specimens I have collected since 2014 (all but 2 since 2018).

Thanks, Tristram! That phenogram looks like one for the ubiquitous Phaonia tuguriorum, a species that can be seen all the year round here, but typically in the colder months (first sighting here on January 2nd).
