Heliconius hecuba apparently flies at elevations of about 2000 meters,
very localised. it flies with Elzunia humboldt in the 9 de Octubre and the Rio Negro areas, the two species being quite similar ; but the two forms that fly near Rio Negro are quite different from those from 9 de Octubre !
Heliconius hecuba has many subspecies (or forms ?) with small and intricate geographic zones; the form from Quebrada Cugusha could be bomplandi ? so could be the one from rio Paute even if it is always slightly different ? see https://www.sangay.eu/en/fiche-papillon/011-Heliconiidae/_/_/015-Heliconius/025-hecuba/choarina+
