Treble Brown Spot - Idaea trigeminata
Wingspan 23 to 25 mm. Usually unmistakable. The main diagnostic feature is a dark brown outer cross band pinched in two places on an otherwise rather plain whitish forewing.
Found around woodland edges and hedgerows.
The adults are on the wing from late May to early July, and can be attracted to light.
The caterpillars feed on Ivy, Knotgrass and other low-growing plants.
Local, mainly occurring in the southern parts of England and Wales. In a recent survey to determine the status of all macro moths in Britain this species was classified as local.
It appears to be uncommon in Leicestershire and Rutland, where there are few records. L&R Moth Group status = D (rare or rarely recorded).
