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 →

With luck
About 10% of wildlife watchers report a Common Lutestring sighting in Liverpool on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 458th most-seen of the 632 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a Common Lutestring in Liverpool on a given day, against under 5% in August to June, 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.
Only Liverpool, in our data

GBIF citizen-science records
It is estimated from how often the Common Lutestring is recorded against all the insects logged in Liverpool (10 verified sightings), 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.
