Hello syrphidae-forum, This syrphidae I found near Amsterdam some weeks ago. there was a lot of rain and the fly became a bit wet. I took several pictures, trying to identify this fly. On these I can see that the pterostigma in the wing is more long then broad I see some hairs on the eyes The first tarsus seems to be dark.. Perhabs this is a female eristalis abusiva? or eristalis arbustorum? It would be nice to dissolve this mystery robert heemskerk Robert Heemskerk attached the following image:  [98.27Kb] |

Hi Robert - The very short-haired arista, dark hind tibia and tarsus, pale middle tibia, and narrow facial stripe all suggest Eristalis abusivus. E.arbustorum has longer hairs on the arista and a much darker mid tibia.
