Haworth's Minor Noctuidae

Celaena haworthii (Curtis, 1829)

Description: Wingspan 25-32 mm. Forewings reddish brown with a series of small black marks along the costa. Stigmata ochreous white and clearly defined the orbicular being quite small. Antemedian and post median lines indistinct. There is a whitish suffusion at the terminal area of the forewing. There is also a series of small black dashes along the outer margin of the wing. Hindwings pale fuscous becoming lighter towards the basal area.

Key Identification Features:

Sets:  male upperside

Flight Period: Late July to the latter part of September.

Status: Widely distributed across southern counties especially around the bogs and fens of north Armagh. In Fermanagh it is found in several widely scattered sites while north of Lough Neagh it has only been reported from coastal localities including Rathlin Island, Antrim. It may possibility be under recorded in some other areas since there is no shortage of suitable habitat.

Ecology: A small species found mainly on bogs, fens and moorland. Adult males will often fly in late afternoon sunshine but the majority are seen at light. Some may be found at rest on the stems of heather. They are also attracted to the flowers of heather Calluna vulgaris, Common Ragwort Senecio jacobaea and wood-rush Luzula spp. The larvae feed during the warmer days in spring through until July on cottongrass Eriophrum spp. and rush Juncus spp. It overwinters as an egg.

World Distribution: Eurasiatic: common across most of western Europe from Portugal north to Denmark and central Fennoscandia.
