Lycophotia porphyrea
In 3 days ~40% in a week ~70%
The true lover's knot (Lycophotia porphyrea) is a moth of the family Noctuidae. The species was first described by Michael Denis and Ignaz Schiffermüller in 1775. It is found in the west Palearctic in a wide band through northern, central and eastern Europe and Russia (up to the Ural Mountains). In the south it is spread through northern Spain and northern Portugal, northern Italy, Macedonia, Bulgaria, and northern Greece. In Europe it is found wherever its food plants grow. It is traditionally thought of as a species typical of heathland and moorland but it can often be found in places where heather and its relatives are in garden cultivation, or sunny slopes and forest edges. In the mountains it is found up to an elevation of over 2000 metres above sea level.
This is a small but attractive species, with a wingspan of 26–34 mm (individuals hatched in higher altitudes tend to be smaller than those from the lowlands). The forewings are brown, often tinged with purple and marked with a complex pattern of white markings which are supposed to recall a true lover's knot. The hindwings are grey or buff. It flies from the latter half of June to the beginning of August and is attracted to light and the flowers of its food plants. Wikipedia →

GBIF citizen-science records
It is estimated from how often the True Lover's Knot is recorded against all the insects logged in Snowdonia National Park (28 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.
