The wingspan is 7–9 mm. The forewings are orange red, but blackish at the base and apical angle. There is a pattern in the form of five silver spots and an incomplete band at the base. Adults are on wing from May to July.[3]

The larvae feed on Stachys alopecuros, Stachys officinalis and Stachys sylvatica. They mine the leaves of their host plant. Young larvae create a mine which consists of a large blotch with lobe-like extensions. Later instars create a dense spinning at the underside of the leaf which is connected to the blotch. Most frass is ejected out of the mine, but some is deposited in a broad line in the centre of the blotch. Often, several mines are found in a single leaf. Pupation takes place outside of the mine in the spinning or in a leaf fold.[4] Larvae can be found from August to September. The species overwinters in the pupal stage.
