Day 171 - Flies

[wolfsbride]

I have a lot of what I've been calling square flies because they seem to fly in a pattern of squares. Does anyone know the actual name? Or have even seen them? They're probably 1/8 of an inch to 1/4 of an inch long. And I think they have double wings that stick straight out like a dragonfly's. Though that's only when they're flying. I've never actually seen one light on something.
