Status and Distribution
Local across most of southern and eastern England and the Channel Islands where it can, on occasions, be locally common. Local to very local in the Midlands and northen England, scarce in Scotland with an old record from Berwickshire and a single post 2000 record from Dumfrieshire. Not recorded in Wales and apparently absent from Ireland and the Isle of Man.
The moth may, on occasions, disperse to find suitable new habitat having been found in a garden where the foodplant became temporarily established.

Finding the Moth
Larva: feeds within a silken tube at the base of the stem and partially underground; the tube sometimes extends higher up the stem.
Adult: flies, making short darting flights, in warm weather during the afternoon and comes readily to light. Can be smoked out from amongst the foodplant.
Can usually be recognised by the prominent brush of brownish scales on segment two of the labial palps, the often dark striped veins of the forewings and by the yellow tip on the underside of the abdomen in the male. Worn or very weakly marked specimens may require dissection.
Double-brooded, from late April to the early June and late June to early September.
