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 →

Rare
Under 5% of wildlife watchers report a Fiery Skipper sighting in Boston on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 783rd most-seen of the 1200 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Fiery Skipper in Boston on a given day, so our monthly data shows no clear season.
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.
45th of 45
Of the 45 cities where we can rate Fiery Skipper sightings, Boston ranks 45th at under 5%. 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 Boston (family Hesperiidae, Skippers) are Zabulon Skipper (about 20%), Peck's Skipper (about 10%) and Silver-Spotted 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 Boston (9 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.
