I think female E. tenax is correct, but I cannot exclude E. similis without a more frontal view of the eyes: tenax 2 vertical bands or a lateral view of the hind tibia: tenax completly black

I am 99,9% sure, it is E. tenax (date!). But hover flies should better be posted in the Syrphidae subforum... Best regards, Jürgen -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Juergen Peters Borgholzhausen, Germany WWW: http://insektenfo... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= |
