Genus Polypedilum
Male abdominal tergite 8 triangular (most distinguishing feature):

Male flagellum 13-segmented (typical for Chironomini, but the common Chironomus group of genera has an 11-segemented male flagellum). Pulvilli deeply divided (requires microscope).

Color varies widely within the genus, from pale to dark. Some species have spotted wings. A few species have hairy wings; this is very unusual within Chironomini though common in Tanytarsini (which may also have triangular 8th tergite).
Larvae are aquatic, like all Chironominae, and are often wood or leaf miners. P. ontario is often found in pupal cases of hydropsochid caddisflies; some other speces are associated with Psilotreta.(1)
One of the most widespread and speciose genera of Chironomidae.
