The great European spruce bark beetle (Dendroctonus micans) was first identified as a breeding species in Britain in 1982. This insect’s distribution, pest status, biology, life cycle and control methods are described. Although its present population is limited to Wales, the English West Midlands and Lancashire, it is well established. Infestations are characterised by scattered groups of attacked trees which display symptoms of resin bleeding and resin tubes upon their trunks.
