The fiery skipper (Hylephila phyleus) 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.
Phylogenetic and genetic analysis of the fiery skipper revealed three haplotypes (HphH1, HphH26, and HphH31) to be shared in roughly 64.1% of all sampled individuals. Due to this high percentage, these haplotypes likely serve as central haplotypes from which different variations via mutations occurred. Haplotypes HphH22 and HphH23 were found in addition to HphH1, HphH26, and HphH31 to occur in species across all continents with certain haplotypes being prominent in different regions. More variation in haplotype may be observed in South America, suggesting populations may be larger and contain more diversity when compared to those of North America. Wikipedia →

With luck
About 10% of wildlife watchers report a Fiery Skipper sighting in Philadelphia on a given day, based on 32 verified sightings from GBIF citizen-science data. It is the 177th most-seen of the 632 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.
August to October
In those months about 10% of wildlife watchers report a Fiery Skipper in Philadelphia on a given day, against under 5% in November to July, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Fiery Skipper sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
40th of 45
Of the 45 cities where we can rate Fiery Skipper sightings, Philadelphia ranks 40th at about 10%. The best odds are in Mesa (United States, about 30%), Tijuana (México, about 20%) and Austin (United States, about 20%).
Same family: Hesperiidae
The closest relatives of the Fiery Skipper that you can see in Philadelphia (family Hesperiidae, Skippers) are Silver-Spotted Skipper (about 20%), Zabulon Skipper (about 10%) and Peck's Skipper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Fiery Skipper is recorded against all the insects logged in Philadelphia (32 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.
