Identity and first report of the four-spotted moth, Palpita quadristigmalis (Lepidoptera: Crambidae), as a pest of Japanese privet, Ligustrum japonicum Thunb. (Oleaceae) in Mexico.

Interpretive Summary: Many species of snout moths in the family Crambidae are pests of crops and ornamentals. One species, the four spotted moth, feeds on privets and olive trees and is reported for the first time causing economic damage on Japanese privet in Mexico. The species was identified using morphology and molecular data and images of adults, larvae, and damage are provided for their identification. This information will be used by horticulturalists, biological control workers, and quarantine personnel.
Technical Abstract: Japanese privet is widely planted as an ornamental and shade tree in Mexico. In 2017, we discovered lepidopterous larvae causing severe defoliation on ornamental privet in Saltillo, Mexico. It was preliminarily identified as Palpita sp. using external morphology. Larvae were reared to obtain adults, and then identified as P. quadristigmalis Guenée (Lepidoptera: Crambidae) using morphology and COI sequences. Larvae of the four-spotted moth, P. quadristigmalis, are defoliators and leaf-folders of trees and shrubs, and among their main hosts are olives and privets (Oleaceae). This is the first confirmed report of P. quadristigmalis causing economic damage in Mexico.
