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.[2] It was transferred to genus Burnsius in 2019, and was previously known as Pyrgus oileus.[3]

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.
