Enyo lugubris, the mournful sphinx, is a moth of the family Sphingidae. It is found from Argentina and Paraguay to Uruguay, Venezuela, Guyana, Suriname, French Guiana, Colombia, Ecuador, Peru, Brazil and the West Indies through Belize, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica and Panama to Mexico and the United States, where it has been recorded from Arizona east to Florida and north to South Carolina. Strays have been recorded from Arkansas, north to Illinois, Michigan and New York.
The wingspan is 50–60 mm. Adults are on wing year-round in the tropics (including southern Florida and Louisiana). Further north, they are on wing from August to November. The larvae probably feed on Vitus tiliifolia and other Vitaceae species, such as Vitis, Cissus and Ampelopsis. In Florida larvae have been reported on Cissus sicyoides and Ampelopsis arborea.

GBIF citizen-science records
It is estimated from how often the Mournful Sphinx is recorded against all the insects logged in Yasuní National Park (5 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.
