Coenonympha california, also known as the California ringlet or common ringlet, is a species of butterfly native to North America. Although it has previously been considered a subspecies of Coenonympha tullia, genetic testing suggests it is a separate species.
Extreme phenotypic variation across several geographic ranges and subspecies populations characterizes Coenonympha california's wing shape. The wings' dorsal ground color varies, ranging from mild ochre, deep orange-ochre, yellow, and pale/white. An inconsistent presentation of submarginal eyespots, called ocelli, on the ventral hind wings closely correspond with this variation. Some butterflies can have many well-developed, dark ocelli within a single location, or they can have none at all. Additionally, the species exhibits localized intergradation, where characteristics like eyespot count and ground color create wide, continuous geographic clines instead of distinct morphological boundaries between nominal subspecies.
Coenonympha california contains the following subspecies: Coenonympha california mcisaaci Coenonympha california galactinus Coenonympha california benjamini Coenonympha... Wikipedia →

Rare
Under 5% of wildlife watchers report a Common Ringlet sighting in Boston on a given day, based on 33 verified sightings from GBIF citizen-science data. It is the 342nd most-seen of the 1200 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.
May–June and August
In those months about 10% of wildlife watchers report a Common Ringlet in Boston on a given day, against under 5% in July and September–April, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Common Ringlet sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 10
Of the 10 cities where we can rate Common Ringlet sightings, Boston ranks 7th at under 5%. The best odds are in Calgary (Canada, about 10%), Toronto (Canada, about 10%) and Edmonton (Canada, about 10%).
Same family: Nymphalidae
The closest relatives of the Common Ringlet that you can see in Boston (family Nymphalidae, Brush-footed Butterflies) are Monarch (about 30%), Red Admiral (about 20%) and American Lady (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Ringlet is recorded against all the insects logged in Boston (33 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.
