It’s called a Peacock Fly (Callopistromyia annulipes) and its dazzling appearance is just amazing. I especially like the blue glossy wings.
If anyone knows something – ANYTHING – on this fly then please leave a comment! Thank you!
Edit: thank you Jason Ralls and Jim for letting us know that this fly is in the family Ulidiidae, which are also known as the picture-winged flies! I guess they’re found in the eastern U.S. and Canada and are either herbivores or saprophagous (feeding on dead or decaying animal matter). You guys rock!
