Xyleborinus saxeseni (Ratzeburg, 1837) - (lesser shot-hole borer)

This ambrosia beetle is native to Europe, Africa and Asia, but introduced in the Americas and some parts of the Australia/Pacific region. It attacks various forest and orchard trees, for example apple, cherry, plum, and apricot. Typically, dying, newly killed or freshly felled trees are attacked. Infested trees will decline, wilt and finally die.

Adult females are around 2½ mm long, cylindrical and black to brown in colouration. Males are only 1½ mm long, flightless and have a lighter colour.
