Introduction

This widespread, geographically variable butterfly (see map 2 below) is involved in Müllerian mimicry with the concordantly variable Heliconius melpomene over most of its range. Only H. erato chestertonii Hewitson does not have a corresponding H. melpomene co-mimic. That race, from the upper Cauca valley of Colombia, is a co-mimic of H. cydno weymeri Staudinger.

Etymology: ERATO was one of the nine Muses, the  goddesses of music, song and dance. Her name means "the lovely" or "beloved" from the Greek word eratos. In Classical times, when the Muses were assigned specific artistic spheres, she was named Muse of erotic poetry and mimic imitation and represented holding a lyre (ERATO).

Characteristics

Early stages:  Eggs are yellow and approximately 1.5 x 0.9 mm (h x w). Females usually place eggs singly on growing shoots of the host plant. Mature larvae have a white body with black and orange spots, black scoli, and yellow head; length is around 1.3 cm. Caterpillars are solitary (Brown, 1981). Pupae are brown with gold spots on the dorsum, the thorax is strongly bowed and has short abdominal spines. The head has long head horns and the antennae have many short black spines (Brown, 1981; DeVries, 1997).

Geographical Distribution

Heliconius erato is widespread throughout Central America and South America. The map below shows an approximate representation of the geographic distribution of this species. The original data used to draw these maps are derived from Brown (1979) which is available at Keith S. Brown Jr. (1979). Ecological Geography and Evolution in Neotropical Forests.

Habits

H. erato occurs from sea level to 2,300 m in forest edges.  Usually individuals fly erratically and in the lowerstory. The males sit on female pupae a day before emergence, and mating occurs the next morning, before the female has completely eclosed. Adults roost at night in small groups 2-10 m above ground in twigs or tendrils (Brown, 1981).

Host plant: H. erato larvae feed primarily on plants from the subgenera Granadilla, Tryphostemmatoides, and Plectostemma (Passifloraceae) (Brown et al., 1977). In Costa Rica H. e. petiverana feeds on Passiflora talamancensis, P. coreacea, and P. biflora (DeVries, 1997).

Geographical Races

Distribution of Heliconius erato geographical races of Central America and the trans-Andean and the upper Amazonian regions of South America, and the closely-related H. himera (black asterisks). Symbols indicate distinct phenotypes, but some phenotypes, such as those indicated by the black and green circles, represent multiple allopatric races. Wing patterns of geographical races of H. erato are relatively uniform throughout their ranges, except where they overlap with adjacent races. In these regions, they freely hybridize, producing a hyperdiverse array of F2 and F1 backcross wing pattern phenotypes. Stippled areas of the map indicate mountainous regions uninhabited by H. erato.

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
