ver-gris du trèfle

The clover cutworm (Anarta trifolii) is a noctuid moth in the family Noctuidae, order Lepidoptera, with a wide distribution spanning Europe, Asia, Africa, and North America. The species has a characteristic cutworm larva that severs plant stems near the soil surface or feeds on leaves and developing seeds, causing significant damage to crops. Primary host plants include clover (Trifolium), alfalfa, beet, and various other broadleaf crops and weeds, making A. trifolii an agricultural pest of moderate to significant importance in affected regions. Adults are brownish-grey moths with subtle wing patterns typical of the noctuidae family, and like most noctuids, they are nocturnal and attracted to light sources. The species is highly mobile, with adults capable of long-distance migration that enables rapid colonization of new agricultural areas. A. trifolii inhabits a broad range of open habitats including agricultural fields, meadows, steppes, and disturbed grasslands across its extensive range. Its polyphagous larval diet and migratory adult behavior contribute to its wide geographic range spanning multiple continents. In Europe, it is found from the Mediterranean to Scandinavia; in North America it occurs in both Canada and the United States. A. trifolii is classified as Least Concern on the IUCN Red List, with populations considered stable and the species benefiting from the widespread availability of agricultural host plants. Natural enemies include parasitoid wasps and tachinid flies, along with pathogens including nuclear polyhedrosis viruses used in biological control.
