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 →

Rare
Under 5% of wildlife watchers report a Common Lutestring sighting in Pyrénées National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 806th most-seen of the 1277 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April, June and August
In those months about 10% of wildlife watchers report a Common Lutestring in Pyrénées National Park on a given day, against under 5% in May, July and September–March, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Common Lutestring sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
4th of 4
Of the 4 parks where we can rate Common Lutestring sightings, Pyrénées National Park ranks 4th at under 5%. The best odds are in Wadden Sea National Park (Germany, about 10%), Cairngorms National Park (United Kingdom, about 10%) and Bavarian Forest National Park (Germany, about 10%).
Same family: Drepanidae
The closest relatives of the Common Lutestring that you can see in Pyrénées National Park (family Drepanidae, Hooktip and False Owlet Moths) are Peach Blossom Moth (about 10%), Buff Arches (about 10%) and Oak Hook-Tip (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Lutestring is recorded against all the insects logged in Pyrénées National Park (9 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.
