Similar species: 1803 Small Rivulet.

Davey, P., 2009: A species found over much of Britain, but local in northern Scotland, the larva feeding in the flowers and seed capsules of red campion (Silene dioica). In Dorset, the moth is at low density but widespread, frequent in the west and north but becoming scarcer further east, typically occurring on hedgebanks and in woodland where Red Campion abounds.

Care is needed in identifying potential Rivulet as they superficially resemble the Small Rivulet¹⁸⁰³. Diagnostics include: a larger species; emerges up to a month earlier; the single circular indentation two-thirds of the way down the postmedian fascia on this species is diagnostic (compare with the double indentation half-way down on the Small Rivulet¹⁸⁰³).
