Subfamily: Mycetophinae, likely Anatella sp.
It's warmed up a bit and has been raining lately. Lots of small flies around the compost. Here's one that I found today that I think is a new family in the yard. Looks like a fungus gnat to me (Mycetophilidae), but I could be wrong about that. I captured one to ID later. ~ 5 mm pic.twitter.com/KDpvLRyC5e— Steve Wells (@swells_LQA) March 2, 2022
