July Belle Geometridae

Scotopteryx luridata (Fabricius, 1775)

Description: Wingspan 32-38mm.

Similar Species: Adults are similar in colour to the Lead Belle S. mucronata scotica however, the discal spot on the forewings lies, in most cases, closer to the antemedian line. Careful examination is required with this species in view of its scarceness and where it overlaps with the closely related Lead Belle.

Key Identification Features:

Sets:  male upperside

Flight Period: From late June to the end of July.

Status: Widely distributed but more local than the Lead Belle. It has been recorded more recently in southern counties, particularly from coastal localities in Down, such as Glasdrumman and the Mourne Coastal path, where it seems to have established populations; many of the recent records are from this general region. It has been taken inland at Brackagh Moss, NNR, Peatlands and the Forkhill/Crossmaglen area of south Armagh, back in the early 1990s. North of Lough Neagh it has been taken at Castlerock Londonderry.

Ecology: Generally much scarcer than the Lead Belle although it does share similar habitats. The larvae share the same characteristics and foodplants as the Lead Bell. It overwinters as a larva.
