Wingspan 12–16 mm. A brown species with prominent glossy ochre tips to the scales from the wing base that give it a more peppered appearance than most other Dichrorampha species. Silvery and grey banded cilia. The pale costal strigulae are conspicuously present from one third, or less, subtending oblique plumbeous striae. The termen has prominent black spots.
Genitalia dissection is required to confirm identification.

Observed on
