Interlopers in the Moth Trap

Last week there was more diversity in the light trap, and actually not so many moths. There were three ground beetles, two of which were of the type pictured, which I believe (based on the shape of the pronuptum) is Ophonus rufibarbis - this genus of beetle is apparently quite often attracted to light. I’m not sure if was the beetles (which are predators) or some ants that also got into the trap, but all that was left of this mayfly was its rather beautiful wings. From the pattern on the wings, these are all that’s left of a Green Drake Mayfly (Ephemera danica), though I would like to catch another sometime so I can see the whole creature.
