Orthotomicus longicollis
Bark beetle Orthotomicus longicollis
Starting from their large nuptial chamber, 2-4 females excavate irregular maternal galleries between the bark and the wood, often cutting across each other. The larvae feed in the bark without leaving gallery marks in the wood. The 3-4 mm long bark beetles usually colonise the stems of greatly weakened pines and are therefore of minor importance in most of Europe. It occurs mainly in pure pine forests.
