Short description: Species of moth

Epermenia insecurella, the chalk-hill lance-wing, is a moth of the family Epermeniidae. It is found in most of Europe, Asia Minor, the Near East and Mongolia.^[2]

The wingspan is 9–11 mm.^[3] The moths fly during the day and can be found on the wing in two generations, between May and August^[4]

The larvae feed on bastard-toadflax (Thesium humifusum) and Thesium inophyllon. They initially mine the leaves of their host plant. Young larvae make a small, full depth, irregular corridor mine. Older larvae live free on the host plant. Larvae can be found from April to June and again in July. They are yellow with a shining black head.^[5]
