Aleuron chloroptera is a moth of the family Sphingidae. It was described by Maximilian Perty in 1833, and is known from southern Mexico, Brazil, Belize, Guatemala, Nicaragua, Costa Rica, Colombia, Peru, Bolivia, Venezuela, Guyana, Suriname, French Guiana, Paraguay, Argentina and Ecuador. It is probably also present in Uruguay, Honduras, El Salvador and Panama.
The wingspan is 64–70 mm. Adults are on wing at least from April to January. In Costa Rica adults have been recorded in January, from April to August and from November to December. Adults feed on the nectar of Callianra, Inga and Duranta species.
The larvae feed on Curatella americana, Davilla nitida and probably other Dilleniaceae species. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Aleuron chloroptera is recorded against all the insects logged in Braulio Carrillo National Park (7 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.
