Overview |
|
|||||||
Oncopsis is a large genus of typical leafhoppers. It occurs in Europe, Asia, and North America. In the United States it occurs in the east from Maine to South Carolina, west to Minnesota and Illinois. It also occurs on the West Coast from northern Washington to southern California. There are 81 Oncopsis species worldwide, at least 30 species in North America north of Mexico, and at least 5 species in Minnesota. |
||||||||
Adults and nymphs are found on trees in the genera Betula, Alnus, Carpinus, Corylus, and Ulmus. |
||
Description |
||
The face is longer than wide or as wide as long. The exoskeletal plate on the first segment of the thorax (pronotum) is densely and conspicuously grooved (striate). The striations are irregular, wrinkle-like, and are parallel with the rear margin of the pronotum. The forewing has 2 or 3 small, interior (anteapical) cells before the cells at the wingtip. There are two subgenera of Oncopsis. In subgenus Oncopsis, the face is longer than wide, and the forewing has 3 anteapical cells. In subgenus Parasitades, the face is as wide as long, and the forewing has 2 or 3 anteapical cells. Identification to species level is sometimes difficult, requiring microscopic examination of the male genitalia. |
