Your letter to the bugman: Hello there. Can you please help me identify this fly?
I found it in the kitchen after a party and it appeared to be sucking the surface of the cake lid.
I lifted it outside and it is still there this morning.
Is it friend or foe? I’d like to help it if needs be.
How you want your letter signed: Victoria
This is a female March Fly in the family Bibionidae, a group sometimes called St. Mark’s Flies in the UK, though that common name might refer to only a single species in the genus Bibio. Based on images posted to NatureSpot, your individual might be Bibio johannis, or possibly Bibio pomonae, the Heather Fly.
