Burnsius philetas
Desert Checkered-Skipper
Burnsius philetas, the desert checkered-skipper, is a small skipper butterfly (wingspan 25–29 mm) found in arid regions of the southwestern United States and northern Mexico. Formerly classified under Pyrgus, this species was reassigned to the genus Burnsius based on molecular and morphological evidence. It exhibits multiple generations per year with activity extending from early spring through late fall, with timing varying by latitude and elevation. The species is notable for its checkered wing pattern and association with dry, open habitats.
