Oak Processionary Moth

Oak Processionary Moth (Thaumetopoea processionea) is a native species of central and southern Europe. The larvae (caterpillars) feed on the foliage of many species of oaks. The first case in Ireland was recently spotted in a Dublin park and has reportedly been traced to a recent import of oak trees from Belgium. Up to now Ireland had Protected Zone Status for this pest.
