Hi,
Ivy (
Hedera helix) flowers attract several syrphids, many
Syrphus representatives among them. I remember that colouration of the hind femora is important for species discrimination, but I am not sure if these are dark enough for
S. vitripennis. So please help me to learn more about the genus.
Thanks, Sundew
