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.

Rare
Under 5% of wildlife watchers report a Tropical Checkered-Skipper sighting in Rio de Janeiro on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 119th most-seen of the 169 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.
January, May, July and November
In those months about 10% of wildlife watchers report a Tropical Checkered-Skipper in Rio de Janeiro on a given day, against under 5% in February–April, June, August–October and December, 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.
26th of 29
Of the 29 cities where we can rate Tropical Checkered-Skipper sightings, Rio de Janeiro ranks 26th at under 5%. The best odds are in Santo Domingo (Dominican Republic, about 30%), Valencia (Venezuela, about 20%) and Caracas (Venezuela, about 20%).

GBIF citizen-science records
It is estimated from how often the Tropical Checkered-Skipper is recorded against all the insects logged in Rio de Janeiro (6 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.
