Scopula immorata, the Lewes wave, is a moth of the family Geometridae. It is found throughout Europe and the Near East. The wingspan is 20–27 millimetres (0.79–1.06 in). The moth flies in two generations from the end of June to mid August in western Europe.
The larva feeds on various low-growing plants like thyme and oregano. Mating occurs from the males seeking out females in simple courtship behavior, taking place at ~6-10am for an hour to an hour and a half. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Lewes Wave is recorded against all the insects logged in Pyrénées National Park (22 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.
