Tribe Chironomini. In North America we have a species of
Polypedlum with similar color pattern. Is tergite 8 anteriorly constricted?

Hello John thank you for the Answer. I searched around and still found pictures of this genre. I searched around and still found pictures of this genre. I have attached a picture from May 1st, 2024 from my garden.
Tergite 8 seems narrower to me than Tergite 7. Ultimately it's about whether a family name or a generic name is possible.
Best Wishes Karl.

This looks much more like a
Polypedilum fallax complex member to me.
I don't think this is
Microtendipes.

Is image two meant to be a seperate post? You have two flies here, the top one I'm quite sure is in Polypedilum fallax complex, possibly Polypedilum pedestre, while the 2nd one you posted is a Microtendipes. Microtendipes species identification In Europe really needs male genitalia under a microscope.

A good Evening Chiroguy. Thank you for the Answer. Sorry, something got mixed up back then. I probably attached the second picture because, to me as a layman, it looked quite similar.
I will then correctly change the identification to Polypedilum fallax complex, as it was actually about the first photo.
Kind regards Karl.
