It's cold, these days, even when the sun shines. It was cold enough at Mud Bay on Friday afternoon for this fly to prefer his sleep to his safety. He let me come within a couple of inches before he started to walk away, slowly.
Now I have to go look it up on BugGuide. Under flies. It should be easy; I'm sure there will only be a couple dozen to sort through.
I always was an optimist.
