Great picture but sadly no scale. What size is this thing?

Oh, sorry! I ran out with a tape measure to try to get one next to measurements for scale, but sadly it didn't quite work. They range a bit, leg-span appears to be between 1/4" on the small end, to just over 1/2" on the large side. The big ones still have small bodies. Most actually look less like mosquitos and more like small, skinny flies. I'll keep trying to get photos. I forgot I have a couple old yellow sticky traps I never threw out from an indoor fungus gnat infestation last year, and those bugs were smaller and fatter.
