Pyrgus oileus

Above, "white spot just beyond cell-end white bar present and enlarged" and the forewing dark towards the apex (not checkered all the way to the tip) distinguishes this from Common/White Checkered Skippers where they overlap. (1)

Below, checkered pattern on wings is blurred.

Male forewing has a mat of long blue-gray hairs; hindwing of both sexes has marginal and submarginal bands made up of equal-sized spots. Underside of hindwing is pale, often with a strong brown overlay; not much contrast between bands and ground color. (
Southern, mostly coastal plain of southeastern states and west to southern Arizona, southward to Argentina.
Open and disturbed areas such as pastures, brushy fields, wooded trails, thorn-scrub, and roadsides (1)(2)
Yearlong in South Florida, Spring/Summer in the Northern part of its range (1)
Larva feed on plants of the Mallow family (1), including axocatzin (Sida rhombifolia), mallow (Malva), hollyhock (Althaea rosea), velvet-leaf (Abutilon), and malva loca (Malvastrum) (2)
Adults nectar at Sidas and small flowered composites such as Shepherd's needles (2)
