General Comments

Beetle pest of certain ornamental and vegetable species, not known to be present in the UK, but closely related to the Lily beetle, which is widespread. Limited prospects for exclusion given the volume of trade with European countries where it is present as a minor pest and scope for confusion with the Lily beetle. Stakeholder groups may wish to monitor for its presence.
