Hemistola chrysoprasaria (Esper, 1794)
Description: Wingspan 33-40mm. A pale, whitish-green moth, with two median cross lines on the forewings, which are white in colour. The hindwings are slightly angled and have a single white median line. There is a pale whitish fringe on all wings.
Key Identification Features:
Flight Period: In Britain adults are reported from late June to early August. (Skinner, 1984)
Status: Donovan describes this species as being rare and most likely introduced into Ireland on non-native Clematis. The only confirmed records for this species in Northern Ireland date back to 1917/18 from Coalisland, Tyrone. There are several recent reports but these are considered erroneous in the absence of voucher specimens or photographs. The continued existence of the species in N. Ireland requires confirmation.
Ecology: The larvae are best looked for in September and again in late spring. They feed on various species of Clematis, none of which are native in N. Ireland. It overwinters as a small larva.
