Elm Bark Beetle
Scolytus multistriatus
Summary 2
Scolytus multistriatus, the European elm bark beetle or smaller European elm bark beetle, is a bark beetle species in the genus Scolytus. In Europe, while S. multistriatus acts as vector of the Dutch elm disease, caused by the Ascomycota Ophiostoma ulmi, it is much less effective than the large elm bark beetle, S. scolytus.
General description 3
Adults can be about 2.2 - 3.0mm long and are reddish brown in colour. Both males and females will have a cylindrical and narrow spine arising from the anterior edge of the 2rd abdominal sternite (Bright 1976, LaBonte et. al. 2003). Teeth are usually present on the posterior-lateral margins of the 2nd to 4th abdominal sternites (LaBonte et. al. 2003).
Habitat 4
These beetles spend most of their lives around their host trees (Ulmus spp.). Adults will be found on the trees themselves while larvae are always in the wood.
