Heliconius erato

Heliconius erato, or the red postman, is one of about 40 neotropical species of butterfly belonging to the genusHeliconius. It is also commonly known as the small postman, the red passion flower butterfly, or the crimson-patched longwing. It was described by Carl Linnaeus in his 1758 .

H. erato exhibits Müllerian mimicry with other Heliconius butterflies such as Heliconius melpomene in order to warn common predators against attacking, which contributes to its surprising longevity. It also has a unique mating ritual involving the transfer of anti-aphrodisiacs from males to females. Its host plants are various passion flower (Passiflora) vine species.

Recent field work has confirmed the relative abundance of this butterfly.
