If you can’t tell from the picture, it’s a few centimeters in length—very thin with a pair of transparent wings that extend straight backwards past the end of the abdomen. The thorax is brown, and past the point where the wings connect it is long and neck-like, leading to a black head with two long antennae. Can anyone identify this insect?
That appears to be a species of snakefly and the lack of a long needle-like ovipositor indicates that this specimen is a male.
The "kite" rather than rectangular head shape suggests it is in the Raphidiidae.
