The erebid moth Ascalapha odorata, commonly known as the black witch, is a large bat-shaped, dark-colored nocturnal moth, normally ranging from the southern United States to Brazil. Ascalapha odorata is also migratory into Canada and most states of the United States. It is the largest noctuoid in the continental United States. In the folklore of many Central and South American cultures, it is associated with death or misfortune.
Female moths can attain a wingspan of 24 cm. The dorsal surfaces of their wings are mottled brown with hints of iridescent purple and pink, and, in females, crossed by a white bar. The diagnostic marking is a small spot on each forewing shaped like a number nine or a comma. This spot is often green with orange highlights. Males are somewhat smaller, reaching 12 cm in width, darker in color and lacking the white bar crossing the wings. The larva is a large caterpillar up to 7 cm in length with intricate patterns of black and greenish-brown spots and stripes.
The black witch lives from the southern United States, Mexico and Central America to Brazil, and even Argentina. Also, the moth has apparently been introduced... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Black Witch is recorded against all the insects logged in El Vizcaíno Biosphere Reserve (9 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.
