Associated with red-rotten wood on veteran oak trees and fallen branches, it inhabits ancient broadleaved woodland as well as pasture-woodlands.
All beetles that depend on dead wood habitats are threatened by the loss of old woodlands and parklands, due to development or agricultural expansion. Old trees and fallen dead wood are often removed from woodlands, reducing the available habitat for these beetles. Furthermore, the age structure of trees within sites may be skewed, and as a result, a constant supply of old wood may be lost.
