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. The wingspan is 9–11 mm. Adults have been recorded on wing from September to October. The larvae feed on Thesium humifusum. 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.
