|scientific name Coenus |
They can be found in grassy habitats east of the Rocky Mountains in both Canada and the United States.
Adults can be found from June to August.
Genus Coenus Dallas lacks a medial spine on the third abdominal sternite. The rostrum reaches the metacoxae and the cheeks and clypeus are nearly equal in length. The buccual are distinctly lobed on the posterior edge. The interior surface of each femur has a row of widely spaced small spines. The tarsi are three segmented and the coxae touch each other where they attach on the thorax. The lateral edges of the pronotum are sharp and the scutellum is broadly rounded. The different species in Coenus can be distinguished by their ranges, the presence or absence of a tooth on the pygophore and the shape of the pronotal edges. Coenus explanatus occurs in the southeastern U.S. and the edges of the pronotum are concave. Coenus delius occurs east of the Rocky Mountains excluding the southeastern states and has a tooth on the pygophore. Coenus inermis occurs in the southeastern states and is lacking a tooth on the pygophore (Rider 1995).
