Ephyriades brunnea, the Florida duskywing skipper, is a butterfly in the family Hesperiidae. It was first described by Gottlieb August Wilhelm Herrich-Schäffer in 1865. The larvae feed on Barbados cherry (Malpighia emarginata), while wild coffee (Psychotria ligustrifolia) has been noted as an important adult nectar source, along with Bidens alba, Croton granduosus, and Lantana involucrata. The larvae are known to be parasitized by two species of parasitic wasp. It is found in South Florida, inhabiting pine rockland habitats. The species is of conservation concern.
The duskywing skipper has a wingspan of around 1+7⁄8 inches (48 mm). The dorsal side of the male's wing is dark brown with a sheen, and a circle of white transparent spots near the apex with a broad lighter brown margin on the hindwing. The dorsal side of the female's wing is brown with dark mottling and dark outer margins. Females have larger and more numerous dorsal spots than males. When freshly emerged, both sexes have a purplish sheen on the dorsal side of the forewing. The caterpillar is a small and translucent green. The head is black with orange patches on the sides and upper face. A dark line bordered... Wikipedia →

With luck
About 10% of wildlife watchers report a Florida Duskywing sighting in Miami on a given day, based on 78 verified sightings from GBIF citizen-science data. It is the 161st most-seen of the 826 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.
February, April–July and September
In those months about 10% of wildlife watchers report a Florida Duskywing in Miami on a given day, against under 5% in March, August and October–January, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Florida Duskywing sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Miami, in our data
Miami is the only city on Wallace's Line with enough records to rate Florida Duskywing sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Hesperiidae
The closest relatives of the Florida Duskywing that you can see in Miami (family Hesperiidae, Skippers) are Horace's Duskywing (about 20%), Fiery Skipper (about 10%) and Three-Spotted Skipper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Florida Duskywing is recorded against all the insects logged in Miami (78 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.
