Yes, the genus you guessed is right! Considering its head I go for E. biciki male. |

Thanks Valerio, but it's impossible. E. biciki is founded in Finland only once 1930-40 in Kilpisjärvi (northern Finland) and Jyväskylä is in Middle-Finland. Rami |

Eupeodes lundbecki is an alternative : both species are very similar. E. lundbecki, like E. biciki has a wide ocular angle (~120°). E. lundbecki is said similar to a Scaeva in appearance, except that the eyes are bare. Other features that distinguishes it from E. biciki are : wing : covered more than 50 % with microtrichia ; eyes : upper facets larger then lower ones.

I thought about this too, Stephane, but the differences between these two are not finished: when I told about "scutellum" I meant that this one fits, because has only pale hairs, while lundbecki has some black hairs (in Scandinavia at least this features is quite useful. I guess in southern Europe should be different). So, I rejected this option and couldn't find any other

Stephane, another feature is how sternites appear. In E. lundbecki they have oval spots while in E. bicicki they have black bands...quite hard to use without the specimen pinned |

Anyway, Eupeodes, except a few easy species is only reliably identiable under lens. When there are some black hairs mixed with pale ones, there are also only visible under the microscope (it is not possible to be sure of their lack/presence on a 640x400 picture).
