Three weeks, no picture of moth posted by me. Yes, the season is coming to an end, but still some interesting species are still on the wing, as this Asteroscopus sphinx. It came to the light yesterday in Berlin. #teammoth, #moth, #stadtnatur, #berlinbiodiversity, #berlin, #urbanbiodiversity

Jetzt übernehmen die Fridays selbst schon die Kritik der Ignoranten. Nicht die Klimabewegung hat enttäuscht. Sie hat mich und viele andere begeistert. Enttäuscht haben Medien und Mehrheitsgesellschaft, die das für sie teuer errichtete Denk-Mal ohne nachzudenken weggerissen haben weil störend.

My observation of the day: Carabus granulatus heavily colonised by the mite Iphidosoma fimetarium. Naturally, I had no idea which mite this might be - iNaturalist owen_seeman provided the identification. 👍 iNaturalist #stadtnatur, #berlinbiodiversity, #berlin, #urbanbiodiversity

Using fish teeth fossils from lake sediments, we found the haplochromine cichlids diversified quite rapidly and the entire food web evolved within just the first three millennia after the formation of modern Lake Victoria (which started refilling ~ 17k years ago). www.nature.com/articles/s41...

Our son now studies in Freiburg/Breisgau. Good reason for a visit to the city and the Belchen, one of the most important places within the hotspot area for lichens in Germany. Breathtaking indeed, even we found only 60 of the about 1000 species. Some highlights.

Nice Tree of Souls (Hericium coralloides) seen today close to Berlin. Despite intensive search, no Omatikaya Na’vi were seen, but Eywa stopped us to take it home. A strictly protected species here.

Not sure how i find this. Wonderful wild collected lichens to be used short term for decoration.

Eupsilia transversa is a quite common moth in Berlin. It hatches in fall and hibernates as an adult. In German, it's "Satellit-Wintereule" as beside the bright yellow or white spot, there are two satellites – so nice. #teammoth, #moth, #stadtnatur, #berlinbiodiversity, #berlin, #urbanbiodiversity
