Lachesilla pedicularia

This small barkfly could have easily been overlooked among the 21 Ectopsocus that shared the same moth trap, but although I didn't retain any of the Ectopsocus to identify this time, I did notice this one lacked the spots on the wings and therefore could be something different. On closer examination the wing venation was very different. I catch too many Ectopsocus to routinely identify them all and in recent years have therefore tended to ignore them, so it's plausible that I have overlooked other very small barkflies like Lachesilla among them.

The darkened veins weren't super-obvious on this individual but the banded abdomen is clear to see in the photos.
