General Comments

A pest of elms leading to sporadic defoliation in its native habitat and now present in Europe, including the UK. Given its potential spread by hitchhiking, exclusion and eradication are not feasible, but action will be taken against interceptions while there is evidence of limited distribution and to help protect vulnerable areas.
