Ips grandicollis (Eichhoff 1868) - (southern pine engraver)

This bark beetle is found North America and parts of Central America. It is an exotic pest in Australia since the 1940s. Mainly stressed pine trees as well as dying and recently felled pines are attacked. The larvae mine the outer sapwood, contributing to the mortality of weakened trees. Outbreaks can develop after storms damage a larger number of pines. The adults are around 4 mm long and have 5 spines each on the ends of the elytra.
