The fly #Ectophasia #crassipennis (#Phasiinae, #Tachinidae,) has a Palearctic distribution and prefers #warmth. In Germany, warmth-favored areas are populated. Contrary to older literature referring to southern/southwest #Germany, the species also occurs in #Berlin. The #brood lives endoparasitically in #truebugs, often on #Pentatomidae. #Globalwarming favors the expansion of the original distribution of #warmthloving#species. #Biodiversity

Friday Flyday! This Zelia vertebrata bristle fly has all the legs you need. Photo from Tennessee.
Phasia hemiptera ist gut an der fuchsroten Behaarung zu erkennen. Die Männchen gehören mit zu den farbenreichsten Fliegen.

#Wanzenfliegen (Phasia hemiptera) legen ihre Eier an Baumwanzen (Gattungen Palomena und Pentatoma) ab. Die Larven fressen sich anschließend in die Wanze hinein und führen zu deren Tod.
I came across this old photo of a handsome tachinid fly that I never identified. I love the stepped geometric black and white pattern on his abdomen. He's sitting on a wingstem (Verbesina alternifolia).
A handsome "swift feather legged fly" (Trichopoda pennipes). See his elegant fringes?
Dipterists definitely missed a good naming opportunity here. He should have been a "Fast Feather Footed Fly."
A female Gymnoclytia on a daisy. The females are black and white. The males are brown and orange.
This huge—huge! 15–20 mm body length—fly is part a group known as the bristle flies. This individual is from genus Rutilia. The adults pleasantly eat nectar, their babies (less-pleasantly) eat scarabs.
