University of Alberta E.H. Strickland Entomological Museum

Common NameShothole borer. SeasonalityAdults may be found all summer long (depending on growth conditions) but activities generally peak from April to June. If conditions allow for three generations, first adult emergence is usually in March, followed by another in May, and a last one in June (Bright 1976). IdentificationAdults may be completely black, or black with a bit of a red margin around the edges, or reddish brown. Frons are flatten (more so in males) and the ventral abdominal stenites slope up gently to meet the elytra (LaBonte et. al. 2003). They can be around 1.8 to 2.4 mm long (Bright 1976). This species of Scolytus do not have a spine on its abdominal sternites (LaBonte et. al. 2003).
