Platycheirus tarsalis

Description

Platycheirus tarsalis is one of a pair of yellow-spotted Platycheirus species with a strongly protruding mouth and the front legs of the male with only tarsal segments 1 and 2 enlarged and the fore tibiae unmodified. Compared with Platycheirus manicatus, the thorax is much shinier, the abdominal spots are paler (creamy-white) and the spots on tergite 2 are well separated from the hind margin of the segment. Females are more likely to be confused with Platycheirus peltatus but have the femora more extensively dark and the abdominal spots are squarer.

Similar Species
