Burnsius oileus, the tropical checkered skipper, is a species of skipper (family Hesperiidae). It is found in the United States (Peninsular Florida, the Gulf Coast, and southern Texas), south through the West Indies, Mexico and Central America to Costa Rica. It was transferred to genus Burnsius in 2019, and was previously known as Pyrgus oileus.
The wingspan is 32–38 mm. There are four to five generations throughout the year in southern Texas and Florida. The larvae feed on several plants in the family Malvaceae, including Sida rhombifolia, Malva, Althaea rosea, Abutilon and Malvastrum. Adults feed on the nectar of the flowers of Sidas species and small-flowered composites such as shepherd's needles.

Possible
About 20% of wildlife watchers report a Tropical Checkered-Skipper sighting in Iguazú National Park on a given day, based on 34 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 60th most-seen of the 306 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
May and June
In those months about 30% of wildlife watchers report a Tropical Checkered-Skipper in Iguazú National Park on a given day, against about 10% in March, July and October–January, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Tropical Checkered-Skipper sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
5th of 15
Of the 15 parks where we can rate Tropical Checkered-Skipper sightings, Iguazú National Park ranks 5th at about 20%. The best odds are in Jaragua National Park (Dominican Republic, about 40%), Los Haitises National Park (Dominican Republic, about 40%) and El Palmar National Park (Argentina, about 20%).
Same family: Hesperiidae
The closest relatives of the Tropical Checkered-Skipper that you can see in Iguazú National Park (family Hesperiidae, Skippers) are Common Mylon (about 40%), Aspernatus Skipper (about 20%) and Southern Sicklewing (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tropical Checkered-Skipper is recorded against all the insects logged in Iguazú National Park (34 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.
