The Rivulet

    Perizoma affinitata

    GeometridaeABH 70.132 B&F 1802

    Widespread across the county, although seldom recorded in numbers, feeding internally on the seed-heads of red campion, and likely to occur wherever campions are allowed to set seed.  The maps suggest an absence from much of the Levels, which may be under-recording or may be due to lack of suitable foodplant.

    Adult Verification Grade: 2
