Maccaffertium terminatum / lepton
This was a mega challenge but i love the puzzles of Mayfly's. The orange vertex and pale orange/yellow notum i had seen before and i just had to track it down. Because it is a subimago seeing what will be very fine pale black line made this tough. However my conclusion is this a a Maccaffertium terminatum / lepton
