Berlin - August - female
I have trouble understanding how to separate
Eristalinus sepulchralis from
Eristalinus aeneus because I think that the abdomen is not 'completely' shiny in
aeneus. I see alot of photos identified as
aeneus but it looks to be matte black too. The eyes are supposed to be hairy all over for
Eristalinus sepulchralis but I do not see but a few hairs at the very bottom of the eyes on my specimen. In this case, genitalia is better for me so I've dissected the ovipositor. Thus, am I correct with
Eristalinus sepulchralis?
Maybe someone can also help with a second question: what is a difference of the ovipositor of Eristalinus aeneus? Noone draws genitalia for some reason.
Thank You for your Time and Effort.
