Heliconius eratosignis, the eratosignis longwing, is a butterfly of the family Nymphalidae. It was described by Joicey & Talbot in 1925.[1] It is found in the South-Western Amazon basin, from Brazil to Peru and Bolivia.[2] The habitat consists of sandy rainforests.
The larvae are gregarious and feed on Passiflora subgenera Astrophea and Mitostemma species. Full-grown larvae have a yellow body with black bands and a black head.[2] 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;[2] in contrast, H. eratosignis has a solid orange basal costal margin on the underside of the forewing. Brown & 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 [3]. 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 [4].
Etymology
The species is presumably named because it is difficult to distinguish from Heliconius erato (as well as from its sister species Heliconius demeter).
