Local in water meadows, marshes, river-banks and damp areas throughout much of England and Wales. The most likely confusion species is
Udea lutealis, in which the cross-lines are more intricately sinuate, the stigmata are larger and clearly outlined, and there is a dark cloud in apex of hindwing [Goater]. Could also be mistaken for the extremely rare
Paracorsia repandalis. Wingspan 22-25 mm. Larva feeds on Common Fleabane and Ploughman's-spikenard, living between leaves spun together with silk.
