Chlosyne nycteis, the silvery checkerspot, is a species of Nymphalinae butterfly that occurs in North America. In the United States, it is listed as a species of special concern in Connecticut and Maine, and is believed to be extirpated in Connecticut, Massachusetts, and New Hampshire.
The dorsal view is pale yellow-orange with dark borders and markings. The hindwing has white-centered submarginal spots on both sides, dorsal and ventral. The hindwing is pale and has a white crescent at the margin. The caterpillar is almost all black with dusted white spots. Sometimes, it has a yellow-orange stripe or two smaller stripes along the side. The family Nymphalidae is known for its branched spines.
Their range consists of southern Canada south to Georgia, Florida, and Texas. Silvery checkerspots enjoy moist areas such as streamsides. They can also be seen in meadows and forest openings. In the northern portion of its habitat, one brood hatches between June and July; for the remainder of its range, two broods occur from May to September. Three broods have been reported in the deep southern part of Texas... Wikipedia →

With luck
About 10% of wildlife watchers report a Silvery Checkerspot sighting in Rocky Mountain National Park on a given day, based on 42 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 42nd most-seen of the 191 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.

GBIF citizen-science records
It is estimated from how often the Silvery Checkerspot is recorded against all the insects logged in Rocky Mountain National Park (42 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.
