  • Hylurgopinus

    native elm bark beetles

    Hylurgopinus is a monotypic genus of bark beetles in the tribe Hylesinini. The sole species, Hylurgopinus rufipes, is native to North America and serves as a principal vector of Dutch elm disease. Adults are small, brownish-red beetles that bore into elm bark to construct galleries for reproduction and overwintering.

  • Scolytus schevyrewi

    Banded Elm Bark Beetle

    Scolytus schevyrewi is a small bark beetle native to Asia that has become invasive in North America. It is a documented vector of Dutch elm disease pathogens (Ophiostoma ulmi and O. novo-ulmi). The species exhibits strong attraction to stressed or weakened host trees, particularly Ulmus pumila, and has been observed displacing both native elm bark beetles and the earlier-introduced smaller European elm bark beetle (S. multistriatus) in North America. In its native range, it also causes significant damage to fruit trees including apricot.
