General Comments

Micro-moth pest of lime trees, present in a number of European and Asian countries. Not recorded as present in the UK, although introduction by hitchhiking, in particular, is a risk. Unlikely to cause significant damage to tree health if introduced. Stakeholders may wish to monitor for its presence.
