Lewes Wave Scopula immorata
Wingspan 20-27 mm.
Formerly a rare resident in a single woodland in East Sussex, this species is now believed extinct in Britain, as habitat changes adversely affected the population. The last known record was in 1961.
Abroad the species is found in Europe and Asia, and inhabits dry grassy habitats, where the larvae feed on a number of low-growing plants.
It flies between May and August in one or two generations.
