Dear Sarah,

the first picture shows a female of Eristalis sp.. Perhaps somebody else can say, what species this is.

The second picture is a female of Episyrphus balteatus. This is an unmistacable species and the most abundant hoverfly in middleeurope

Thank you so much for the rapid response Gisela Smile. For curiosity, what are the characteristics which denote a female? Sarah

Dear Sarah,

the eyes of the females are divided by a greater interspace, the eyes of the males join together among the most species (but there are some exeptions). Moreover the genus Sphaerophoria shows a greater sexual dimorphism as the most other Syrphid-species.

Greetings

The female Eristalis most likely is Eristalis pratorum. Maybe you have another picture to post here, with a better look at the eyes and face?

Greetzz, Andr
