Abstract
The Sandhill Rustic moth Luperina nickerlii leechi is an isolate restricted to the beach of Loe Bar in Cornwall UK; it is a UK Priority taxon because of its unique status and small, declining population. The larval foodplant is Sand Couch-grass Elytrigia juncea; the larvae feed at first inside the stems and then on the rhizomes underground. The distribution of the moth and E. juncea were investigated in this study in relation to substrate conditions and other plants. E. juncea has an above-ground clumped distribution; near the sea the plants are linked by rhizomes, but away from the sea the apparent clumping is a probable historic record of previous connectivity where the rhizomes have disappeared. The adult moths were found to be associated with more vigorous E. juncea plants growing in sparsely vegetated, more disturbed ground near the sea, especially those plants with large rhizome systems along which later instar larvae can travel between plants. Emerging moths were associated with areas of extensive E. juncea surrounded by bare ground, where there was a substantial variation of shingle particles between 125 μm and 8 mm. The absence of vegetation and associated roots apart from E. juncea, and a coarse particle mix, may allow larvae to move through the shingle and the moths to push their way upwards from their subterranean pupae. We conclude that management should aim to create areas of bare ground with extensive patches of E. juncea growing in coarser shingle, with extensive underground connectivity and few other plants.
