There are around 28 species in the genus globally across the holarctic region. Only a single species is recorded in Britain and Ireland.
The Eriocampa are characterised by large crater-like punctures on the scutellum and mesopleura. The cenchri are small, triangular in shape and set far apart. The frontal lobe of the mesoscutum is transected medially by a groove with the posterior portion flattened in comparison to the domed anterior portion.
Larvae feed on various trees and are often covered with a waxy secretion.
