The Meadow Sedgesitter (Platycheirus quadratus) is a small, dusky-yellow and black, Nearctic species. Males can be identified by abdomen pattern and flattened front tibia and tarsi (see drawing). Females, patterned similarly to the males, are not easily separable from other Sedgesitter (Platycheirus) species. Adults are commonly found on grass and sedge blades at the edge of ponds and wetlands where they feed on pollen grains.
