Pseudopityophthorus minutissimus
oak bark beetle
Pseudopityophthorus minutissimus, commonly known as the oak bark beetle, is a small bark beetle in the family Curculionidae. It is native to North America and breeds in oak species (Quercus). The species has been investigated as a potential vector of the oak wilt fungus Ceratocystis fagacearum, though evidence suggests it plays a minor role in long-distance pathogen transmission compared to other insects.
