Spongy moth (Lymantria dispar dispar)

Changes to common names

The common names for some insects are under review internationally. Spongy moth is the new common name for Lymantria dispar dispar, previously known as European gypsy moth, EGM or LDD moth. This change does not affect the French name.

The common name for the group of moths (Lymantria dispar asiatica, Lymantria dispar japonica, Lymantria umbrosa, Lymantria postalba and Lymantria albescens) referred to as AGM (formerly Asian gypsy moth) has changed to Flighted Spongy Moth Complex (FSMC).
