Sandhill Rustic Moth

All races of the Sandhill Rustic are nocturnal and single-brooded; adults fly in August and September. They are not attracted by light, but are more likely to be found resting on the stems of the foodplant (2), sand couch-grass (Elytrigia juncea) (4). Caterpillars are present between September and early July, feeding in the stem bases and the tops of the roots of the food plant (2). The overwintering stage is the caterpillar (2).

This race, along with Luperina nickerlii gueneei, another race that occurs in north Wales and Lancashire, is included in English Nature's Species Recovery Programme.

There are four races, or subspecies of the Sandhill Rustic moth in Great Britain (3). Luperina nickerli leechi has silvery-grey forewings, and a brownish band passing across the centre of the wings (2).

Inhabits a sand and shingle beach (3).

This race of the Sandhill Rustic was first found in 1974. It has an extremely restricted range, occurring only in one small site in the south-west of Cornwall (3).

Classified as Endangered in Great Britain (3).

As it occurs at just one site, the population is exceptionally vulnerable to chance events such as storms (3). However, the caterpillars are protected from winter gales because they live at first inside the stems of the foodplant. The other main threat is the encroachment onto the beach of thicker vegetation, especially red fescue grass, with the loss of open areas of bare sand suitable for Sandhill Rustic and sand couch-grass (5).
