Lymantria dispar dispar (LDD) moth

Changes to common names for European gypsy moth and Asian gypsy moth

The common names for the European gypsy moth (EGM) and the Asian gypsy moth (AGM), and other similarly named insects, are currently under review internationally and within Canada, including by the Canadian Food Inspection Agency (CFIA). For now, the CFIA will refer to the EGM as the LDD moth or by its scientific name, Lymantria dispar dispar. The group of moths making up the AGM complex will be referred to by their scientific names, Lymantria dispar asiatica, Lymantria dispar japonica, Lymantria umbrosa, Lymantria postalba and Lymantria albescens, or the short form AGM moth until a final decision on a new common name is made.

The LDD moth (Lymantria dispar dispar) is an invasive pest that can destroy trees by eating their leaves. It is found in Ontario, Quebec, New Brunswick, Nova Scotia and Prince Edward Island. The LDD moth has been detected in British Columbia, Alberta, Saskatchewan and Manitoba, although introductions of the insect have been detected and eradicated.

What to do
