Small Poplar Borer
A smaller relative of S. carcharias with yellowish-green pubescence and a row of spots along the elytral suture. It attacks young aspens and poplars, causing characteristic gall-like swellings on branches. Widely distributed across the Holarctic region.
Did You Know?
The gall-like swellings caused by larvae are sometimes mistaken for plant galls caused by wasps or mites.
