Netted Mountain Moth Macaria carbonaria
(Clerck, 1759)[Synonyms: Semiothisa carbonaria]
Wingspan 23-25 mm.
This small geometrid moth is locally resident in the moorlands and mountains of the Scottish Highlands.
It is a day-flying species and can be found visiting the flowers of suitable plants growing in its favoured habitat. It is quite an early-flying species, being on the wing between April and June.
The small green caterpillars feed on bearberry (Arctylostaphylos uva-ursi).
