D. olerella, which has the forewing with an acutely angled pale fascia at two-thirds, and a dark thorax; the second discal stigma is smaller and less conspicuous than that of

D. olerella. Larva feeds on Wild Carrot, Upright Hedge-parsley, Cow Parsley and Rough Chervil, living between leaves spun together with silk.
