Appearance
Very small with wingspan of 5–7.5 mm in males and 5.5–7.5 mm in females. cream-colored. Forewings narrow, with pattern typical of the .
Habitat
Found in open supporting leguminous vegetation, including grasslands, meadows, agricultural fields, and disturbed areas where clovers and medicks grow.
Distribution
Native to western, central, and southern Europe; extends east to Russia and south to North Africa and the Middle East. Introduced and established in California, United States.
Seasonality
active March–July in Europe; May–June in North America. Larvae present April–May.
Diet
Larvae feed on Medicago sativa (alfalfa), Medicago lupulina (black medick), Medicago polymorpha (bur clover), Trifolium repens (white clover), Trifolium hirtum (rose clover), Vicia americana (American vetch), and Hippocrepis comosa (horseshoe vetch).
Host Associations
- Medicago sativa - larval agricultural crop
- Medicago lupulina - larval
- Medicago polymorpha - larval
- Trifolium repens - larval widespread lawn and pasture
- Trifolium hirtum - larval
- Vicia americana - larval North American native
- Hippocrepis comosa - larval

Larvae found in April and May; and follow. Specific pupal and stage not documented in available sources.
Behavior
Larvae are leaf-feeders on plants. activity presumed based on characteristics, though not explicitly documented.
Ecological Role
Herbivore specializing on Fabaceae; may contribute to of weedy clovers in managed landscapes.
Human Relevance
Evaluated as a potential agent for clovers in California. Not known to cause significant economic damage to cultivated legumes.
