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 →

GBIF citizen-science records
It is estimated from how often the Funereal Duskywing is recorded against all the insects logged in Phoenix (39 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.
