Fiery Skipper

Hylephila phyleus

The fiery skipper is a species of butterfly in the family Hesperiidae. Reaching approximately 1 inch (2.5 cm) in length, male fiery skippers are orange or yellow while the females are dark brown. Small brown spots may be observed on both the hindwing and forewing of both sexes although to a varying degree. Females may be darker brown overall with pale checkered markings on the hindwing. Fiery skipper larvae, or caterpillars, are greenish pink-grey with a black head and constricted neck. These larvae are often considered pests and can feed on Bermudagrass, creeping bentgrass, and St. Augustine grass. Source
