California Sedgesitter
Platycheirus russatus is a hoverfly in the Syrphidae, described by Vockeroth in 1990. It belongs to the Platycheirus, a group commonly known as sedgesitters due to their habit of perching on sedges and other vegetation. The species is known from California and is associated with wetland and riparian . Like other members of its genus, it likely serves as a and may have larvae that prey on aphids.

Identification
Members of Platycheirus are distinguished from other hoverfly by their relatively slender bodies, long legs adapted for perching on vegetation, and often distinctive leg ornamentation in males. -level identification within Platycheirus requires examination of male genitalia and leg modifications. Without specific diagnostic features documented for P. russatus, precise field identification to species is not reliably possible.
