Lopinga achine, the woodland brown, is a Palearctic butterfly in the family Nymphalidae. The forewing length is 19–29 mm. The wingspan of the butterfly is from 45 to 55 millimeters. The wings are grey-brown above and below, with round dark spots of varying sizes in yellow rims on the outer part. On the underside of the wings along the outer edge are yellow lines with a black line between them. Sexual dimorphism is weakly expressed.
P. achine Scop. (= dejanira L.) (45 g). Dark brown: forewing with 5—6 eye-rings forming a chain, hindwing with 2—4 such rings. Underside proximally to the ocelli with a white distal band which is variable and may be so much reduced that the row of ocelli is placed within the ground-colour. Deviations in the band occur especially often in alpine specimens, though singly also in other places, ab. mendelensis Lowe being based on such variation. From West Europe throughout Central and North Europe, Siberia and North China to Japan, northward to Livonia. North Russia and Amurland. southward to Northern Italy. —
In the east of the area there occur specimens with the eye-rings on the upperside enlarged, ab. achinoides... Wikipedia →

Rare
Under 5% of wildlife watchers report a Woodland Brown sighting in Novosibirsk on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 172nd most-seen of the 216 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.
June and July
In those months about 10% of wildlife watchers report a Woodland Brown in Novosibirsk on a given day, against under 5% in August to May, the lowest months. Those are among Novosibirsk's wettest months, with about 65 mm of rain a month against 25 mm in February.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Woodland Brown sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Novosibirsk, in our data
Novosibirsk is the only city on Wallace's Line with enough records to rate Woodland Brown sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Nymphalidae
The closest relatives of the Woodland Brown that you can see in Novosibirsk (family Nymphalidae, Brush-footed Butterflies) are Small Tortoiseshell (about 20%), European Peacock Butterfly (about 20%) and Scarce Tortoiseshell (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Woodland Brown is recorded against all the insects logged in Novosibirsk (6 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.
