= Oedancala dorsalis =

Oedancala dorsalis are found in the super family Lygaeoidea(Seed Bugs) which is one of the largest varied family of Heteroptera (a suborder) of Hemiptera. Seed bugs are a very diverse family of seed feeders found on various types of vegetation.There are four Nearctic species in this genus. O. bimaculate and O. cubana are neotropical species that barely make it into the United States.

Diet, Ecology, and Distribution
Many heteroptera feed on plant juices, are predators, are mixed feeders, and a few are parasites. Oedancala dorsalis, can be found living on the seed heads of Carex and Cyperus both as nymphs (resemble adults except they usually have reduced wings and are incapable of flight)  and adults. The seed heads allow easy camouflage. The life cycle of this species has not been studied in detail, but it is known to be a gradual, incomplete, metamorphosis (no pupa stage). It is a wide range from Quebec and New England west to the Dakotas and Colorado and south to Florida and Texas. Rare in Florida.

Description
They are moderately sized (6-6.5mm) with bright yellowish tinged with brown. Median and lateral pronotal lines, elongate raised calloused spot on either side of midline of scutellum, pale yellowish to almost white. Scutellar surface and claval commissure black. Apical corial margin sometimes infuscated near apex, lacking a dark spot midway along margun. First label segment extending posteriorly at least to anterior margin of eye. O. crassiman looks similar, but its first segment on its antenna is longer, and is found from Maryland to South America.
