In 3 days ~50% in a week ~80%
Hydriomena furcata, the July highflyer, is a moth of the family Geometridae. The species was first described by Carl Peter Thunberg in 1784. It is found in the Holarctic ecozone. It is extremely abundant in northern Europe; in central Europe it becomes more local and in the south it is apparently almost lacking; in Siberia and central Asia it has a wide range. The preferred habitat is moorland areas of sub-alpine and montane regions, hedgerows and woodland margins.
Hydriomena furcata can reach a wingspan of 23–30 mm (0.91–1.18 in). These moths are very variable, both in markings as well as colour. The ground colour ranges from olive green to grey, greyish brown and reddish brown. Also the dark cross bands vary in intensity and pattern. The banding is reddish brown... Wikipedia →

GBIF citizen-science records
It is estimated from how often the July Highflyer Moth is recorded against all the insects logged in Cairngorms National Park (91 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
