Thread subject: Diptera.info :: Many Ectophasia (Tachinidae) from 14.08.19 --> males are all E. crassipennis

Hello,

since my first find in September 2016, Ectophasia has become rather frequent here. Now they baffle me with their variety of wing shapes and wing and abdomen markings. Sometimes I even have problems to tell males and females apart (are there "non-macho" males in Ectophasia like in Phasia?).

Are the flies below all Ectophasia crassipennis? On meadows near a small creek and near a forest (northwest Germany).

Yes, there are non-macho males.
But the wing infuscation should be obvious: only a central dark spot in female, much more extended in male. So, contrary to Phasia, females have partly darkened wings as well !

And yes, crassipennis is very variable and yes, all males shown are crassipennis. Oblonga is red rather than yellow. Females cannot be separated from picture (at least not by me).
