Hello,

after looking at it with the bare eye, I first thought of some small Fannia. But after closer inspection on the PC it turned out to be a little (ca. 4 mm) Phasia. Possibly P. obesa? At night at the door light of our house (northwest Germany). Sorry, only photo.

Hi Jürgen, I think it's P. obesa but you cannot surely exclude aurulans without looking at Sternit 7. The size 4 mm will also point to obesa.

Thanks a lot, Eric and Theo!

Today I also found P. obesa, P. hemiptera and Ectophasia crassipennis by daylight on flowers (and hundreds of Tachina cf. fera).

Great !
Look on Heracleum for the very small barbifrons.
And in 1-2 weeks time, aurgiera should appear.

Hello Theo,

yes, I found it there in big numbers in the last years, but not this year. Only several P. obesa and one or two P. hemiptera yesterday.

And in 1-2 weeks time, aurgiera should appear.

That one was also numerous in the last years (mainly on Mentha), but in 2018 I only found one single male specimen (pic below) - on September, 5th, at rather low temperatures in a forest (!).
