The viceroy (Limenitis archippus) is a North American butterfly. It was long thought to be a Batesian mimic of the monarch butterfly, but since the viceroy is also distasteful to predators, it is instead considered a Müllerian mimic.
The viceroy was named the state butterfly of Kentucky in 1990. Its wings feature an orange and black pattern, and over most of its range it is a Müllerian mimic with the monarch butterfly (Danaus plexippus). The viceroy's wingspan is between 53 and 81 mm (2.1 and 3.2 in). It can be distinguished from the monarch by its smaller size and the postmedian black line that runs across the veins on the hindwing.
In Florida, Georgia, and the American Southwest, viceroys share the pattern of the queen (Danaus gilippus) and in Mexico they share the pattern of the soldier (Danaus eresimus). In all three areas, the local Danaus population mimic the coloration of the viceroy species. It was originally believed that the viceroy was a Batesian mimic of the three other species, and presumed edible or only mildly unpalatable to predators, but this has since proven not to be true. In an experiment with both the monarch's and viceroy's wings removed, birds... Wikipedia →

Possible
About 20% of wildlife watchers report a Viceroy sighting in Congaree National Park on a given day, based on 22 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 50th most-seen of the 145 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
September and October
In those months about 40% of wildlife watchers report a Viceroy in Congaree National Park on a given day, against under 5% in June and November–April, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Viceroy sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 8
Of the 8 parks where we can rate Viceroy sightings, Congaree National Park ranks 3rd at about 20%. The best odds are in Everglades National Park (United States, about 30%) and Big Cypress National Preserve (United States, about 20%).
GBIF citizen-science records
It is estimated from how often the Viceroy is recorded against all the insects logged in Congaree National Park (22 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.
