Yorkshire Status: Common and fairly widespread resident.

This species is present all over most of the county where the larvae feed on red campion. There has been little change in numbers or distribution. It is bivoltine in Yorkshire with two overlapping broods. Take care not to confuse it with the smaller Small Rivulet which emerges later. The usual feature used to separate these two species is the single indentation in the white central band (double in Small Rivulet) but this is not 100% reliable as Rivulet can sometimes show a small second indentation.

Sutton & Beaumont, 1989: Taken occasionally in all five vice-counties wherever its foodplant (red campion) occurs.

Recorded in 135 (68%) of 200 10k Squares.
First Recorded in 1883.
Last Recorded in 2023.
