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 :). 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?
