Platycheirus rosarum

Platycheirus rosarum is a species of hoverfly found in the Palearctic. Like its close relative Platycheirus granditarsus, it can be found in marshy meadows and ditches; indeed, the two species can often be found together. The flight time is between May and October, though it peaks in abundance in June and July.[1][2]

gollark: Seriously. It's not hard. Does TJ09 really not have 5 minutes to add pagination and write up a small paragraph on the rules?!
gollark: Plus UnreasonableLackThereof™

gollark: Would I get banned for `Free, offer 2G prize, ND, CB Gold `? Probably, as I spoke out about the rules.
