Heliconius numata

Heliconius numata, the Numata longwing, is a brush-footed butterfly species belonging to the family Nymphalidae, subfamily Heliconiinae. This species is native to most of South America, from Venezuela to South Brazil (Guyana, French Guiana, Surinam, Guatemala, Venezuela, Ecuador, Bolivia, Brazil and Peru). H. numata is a neotropical species, less common in virgin forest than in areas of secondary growth. It occurs at an elevation of 0–1,800 metres (0–5,906 ft) above sea level in tall forests. Subspecies include: Heliconius numata has a wingspan of 78 millimetres (3.1 in). These very large butterflies have long and rounded wings of brown and orange color, with very variable markings due to its capacity of mimicry with several species. The caterpillar is white with black spots and black thorns. H. numata is known for its mimicry of Melinaea butterflies. Both H. numata and the species of Melinaea it resembles are unpalatable to predators, making this a case of Müllerian mimicry, a mutualistic reinforcement of the same negative signal. Both males and females are attracted to red or orange flowers, or indeed to pieces of cloth colored red or orange. Eggs typically are found on low-growing vines of Passiflora. Caterpillars mainly feed on plants from the subgenera Granadilla, Astrophea and Distephana (Passifloraceae) and from the genera Tetrastyli and Dilkea.
