Dictyacium ambiguum
The photos above were recently identified as Dictyacium ambiguum.
A member of Marsh Flies Family Sciomyzidae

Ah nice! it's not Euthycera arcuata, but a very nice species currently not on Inaturalist :-) Congratulations!

Can you post the other two pictures that are also on bugguide? The current picture on Inaturalist does not allow for species identification :-)

There are two species of Dictyacium in your region, D. firmun and D. ambiguus; which can be separated by the shape of the eye and the colour of the fore basitarsis. Your's is D. ambiguus (as the basitarsus is white, contrasting with black tibia, only visible from other pictures).

wishes,
Jonas
* jonasmortelmans disagrees this is Euthycera arcuata
