What do they do?
They attack a wide range of broadleaved trees, and if they became established in Northern Ireland they would be a significant threat to our horticultural industry, and to trees and shrubs in parks, gardens and the countryside.
The larvae are hard to detect as they feed by tunnelling inside woody trunks and branches, finally emerging as the distinctive, long-horned adult beetle through a round bore hole in the bark. For more information, and what to look out for, please click on the link below
