Tremex woodwasp (Tremex fuscicornis) is an insect pest of Broadleaf trees. It is a native of Europe and Asia.
This wasp prefers stressed trees. In places where it has been introduced, it has caused severe damage to trees of importance in agriculture, arboriculture and forestry. Boring by larvae causes severe degradation of wood, in many cases attacks are so heavy to render the wood useless. This is just one of many forest pests that are moved to un-infested forests by humans moving firewood. Help to protect our forests: don't move firewood!For more information about this plant pest, see the CAPS data sheet.
