  • APHIS Announces New Common Names for Regulated Lymantria Moths

    • Dec 14, 2022

    • USDA. Animal and Plant Health Inspection Service.

    • USDA’s Animal and Plant Health Inspection Service (APHIS) is replacing the common name for regulated Lymantria moths. APHIS will replace "gypsy moth" (Lymantria dispar) with "spongy moth" and "Asian gypsy moth" (L. dispar asiatica, L. dispar japonica, L. albescens, L. postalba, and L. umbrosa) with "flighted spongy moth complex." This change aligns APHIS with the Entomological Society of America’s "Better Common Names Project" and the scientific community. Spongy moths are significant invasive forest pests. They can defoliate hundreds of species of trees and shrubs and harm our country’s natural resources.
