Heliconius eratosignis
Heliconius eratosignis, the eratosignis longwing, is a butterfly of the family Nymphalidae. It was described by James John Joicey and George Talbot in 1925. It is found in the south-western Amazon basin, from Brazil to Peru and Bolivia. The habitat consists of sandy rainforests.

The larvae are gregarious and feed on species in the "Passiflora" subgenera "Astrophea" and "Mitostemma". Full-grown larvae have a yellow body with black bands and a black head. They reach a length of about 20 mm.

Adult "H. eratosignis" are distinguished morphologically from their sister species "Heliconius demeter" because they lack a yellow streak on the base of the forewing costa underside; in contrast, "H. eratosignis" has a solid orange basal costal margin on the underside of the forewing. Keith S. Brown and Woodruff W. Benson in 1975 argued the two forms were the same species, but recorded both "H. eratosignis" gregarious and "H. demeter" solitary larvae in their paper. The Tree of Life Web Project has yet to recognize "H. eratosignis" as a separate species, but shows an image of a male "Heliconius eratosignis" from Peru under the description of "H. demeter".
