May - August. Britain and Ireland. A medium-sized, orange-yellow moth with fine brown wavy lines on the wings. Found in fields, meadows and gardens. Darker races occur on some islands.

The intricate and wavy pattern on this unmistakeable moth resembles that of some seashells giving the moth its name.  There is some geographic variation in colour, from yellow to brown, but the brighter forms are more frequent with the darkest forms occurring on some of the Blasket Islands off the coast of Co. Kerry. Frequently disturbed during the day and flies from dusk onwards.
