Erynnis funeralis, commonly known as the funereal duskywing, is a species of butterfly of the family Hesperiidae. It is found from southern United States (California, Arizona, New Mexico and Texas), south to Argentina and Chile. Strays can be found north up to northern Illinois, north-eastern Nebraska, central Colorado, southern Nevada and central California.
The wingspan is 34–45 mm. They are very similar to the mournful duskywing, but can be distinguished by narrower fore wing with a light brown patch along outer edge. Their wings are black and brown with a white fringe on the hind wings. Adults are seen from February to October.
The larvae have a black head and a green body with yellow hairs and yellow markings. Its host plant is often Medicago sativa. Other plants the larvae feed on include Robinia neomexicana, Medicago hispida, Acmispon glaber, Olneya tesota, Vicia, and Acmispon. Adults feed on flower nectar. Wikipedia →

Possible
About 20% of wildlife watchers report a Funereal Duskywing sighting in Joshua Tree National Park on a given day, based on 56 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 35th most-seen of the 190 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
March
In that month about 30% of wildlife watchers report a Funereal Duskywing in Joshua Tree National Park on a given day, against under 5% in June–August and November, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Funereal Duskywing sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 6 parks where we can rate Funereal Duskywing sightings, Joshua Tree National Park has the highest daily chance: about 20%. Next come Saguaro National Park (United States, about 20%) and Bahía de Loreto National Park (Mexico, about 10%).
GBIF citizen-science records
It is estimated from how often the Funereal Duskywing is recorded against all the insects logged in Joshua Tree National Park (56 verified sightings from 2019 to 2026), 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.
