Polygonia c-album, or the comma, is a food generalist (polyphagous) butterfly species belonging to the family Nymphalidae. The angular notches on the edges of the forewings are characteristic of the genus Polygonia, which is why species in the genus are commonly referred to as anglewing butterflies. Comma butterflies can be identified by their prominent orange and dark brown/black dorsal wings.
Both the larval and adult stages exhibit protective camouflage, mimicking bird droppings and fallen leaves respectively, which reduces predation. The pupae are also cryptic, resembling shriveled leaves. During the later stage of development, the larvae also develop strong spines along their backs. The species is commonly found in Europe, North Africa, and Asia, and contains several subspecies. Although the species is not migratory, the butterflies are strong fliers, resulting in an open population structure with high gene flow and increased genetic variation.
The outer margins of the wings are strongly and irregularly dentate, excavated and angulated. The upper side of the wings has a bright orange color, decorated with brown marks and light spots on the edge. The reverse is... Wikipedia →

With luck
About 10% of wildlife watchers report a European Comma sighting in Bucharest on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 63rd most-seen of the 361 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
June
In that month about 20% of wildlife watchers report a European Comma in Bucharest on a given day, against under 5% in October to February, the lowest months. That is one of Bucharest's wettest months, with about 80 mm of rain against 35 mm in February.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most European Comma sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
27th of 43
Of the 43 cities where we can rate European Comma sightings, Bucharest ranks 27th at about 10%. The best odds are in Liverpool (United Kingdom, about 40%), Manchester (United Kingdom, about 30%) and Birmingham (United Kingdom, about 30%).
Same family: Nymphalidae
The closest relatives of the European Comma that you can see in Bucharest (family Nymphalidae, Brush-footed Butterflies) are Red Admiral (about 10%), Painted Lady (about 10%) and European Peacock Butterfly (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the European Comma is recorded against all the insects logged in Bucharest (23 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.
