Epuraea corticina
Epuraea corticina is a small sap-feeding beetle in the family Nitidulidae, first described by Erichson in 1843. It has been documented in northern North America and is specifically associated with oak wilt fungus mats, where it develops. The species is one of several Epuraea beetles linked to fungal diseases of hardwood trees.
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.
