I’ve had a bunch of these flies in my yard for the past couple of years. I’ve tried to find out what kind of fly this is on my own with out any luck. In fact, trying to I.D. this fly on my own is part of what led me to your site.
Sadly, my camera gave me a hard time with focusing on this fly, so I was only able to get this one picture before it became annoyed with me and flew off. I was hoping that you’d be able to help me I.D. it.
This is a Picture Winged Fly in the family Ulidiidae. The species Delphinia picta does not have a common name. According to BugGuide , it: “Breeds in decaying organic matter, such as compost.”
