Ochropacha is a monotypic moth genus in the family Drepanidae. The genus was first described by Hans Daniel Johan Wallengren in 1871. Its single species, Ochropacha duplaris, the common lutestring, was first described by Carl Linnaeus in 1761. It is found in China (Jilin), Russia, Japan, the Korean Peninsula and from Central Asia to Europe.
The wingspan is 27–32 mm. It is similar to Tetheella fluctuosa but the forewings with the whitish lines usually less distinct, the central band usually dark-striated towards edges, two black discal dots transversely placed, no praesubterminal dash and a dark fuscous oblique apical dash. The larva is pale dull greenish, deeper dorsally; dorsal line darker; subdorsal broad, dull olive-green; lateral line, yellowish; dots black; head reddish.
The moth flies from June to August depending on the location. The larvae feed on birch. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Common Lutestring is recorded against all the insects logged in Bavarian Forest National Park (10 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.
