Eueides heliconioides, Rio Madre de Dios, Peru Adrian Hoskins
Introduction
The tribe Heliconiini, colloquially known as Longwings, includes 71 species, all confined exclusively to the neotropics. The butterflies are characterised by possessing distinctively patterned elongated forewings and a delicate fluttering flight. The Heliconiini includes the genus Heliconius ( 39 species ), together with the smaller genera Dryas, Agraulis, Dryadula, Eueides, Neruda, Laparus, Philaethria, Dione and Podotricha.
The 12 Eueides species are similar to other Heliconiines but smaller in size. Some such as isabella are mimics of tiger-complex Ithomiines, while others including aliphera and lineata are very similar to Dryas and Dione in appearance. A few such as vibilia closely resemble Actinote species. Eueides heliconioides falls into yet another group which strongly resemble Laparus doris. To further confuse matters the butterfly was known by the name Heliconius eanes until the 1970's!
A major characteristic which helps to distinguish Eueides from similar taxa is the shape and length of the antennae - in Eueides these are never more than half the length of the costa; in Actinote they are about the same length but are very strongly clubbed. In the tiger-complex Ithomiines they are long, tapered, cream in colour and dropping. In Heliconius and Laparus they are about two-thirds the length of the costa, and erect.
The underside of heliconioides is similar to that of Laparus doris, but in that species there are white lines radiating to the outer margin of the hindwings, and there is an additional subapical white bar on the forewings.
Eueides heliconioides occurs in Ecuador, Peru and Bolivia.

Habitats
This is a lowland and mid-elevation rainforest species, occurring at altitudes between 100-1800m.
Lifecycle
I have no data relating to heliconioides, but the following generalisations apply to the genus Eueides and are probably relevant : The eggs are greenish white and laid singly on the underside of leaves. The caterpillars are variously coloured but share the characteristics of having a bold lateral stripe, branched spines on the back and sides, and prominent head spines. They feed on the older leaves of Passiflora ( Passifloraceae ) and Erbilichia ( Turneraceae ). The pupae are pale in colour, marked with black specks, and have 4 short forward-pointing spines on the back of the abdomen.
Adult behaviour

Males visit damp sandbanks, peccary wallows, muddy puddles and the edges of small pools and lagoons to imbibe moisture from which they extract dissolved minerals. These are probably passed to females during copulation, and may be essential in the production of viable eggs.

Both sexes occasionally visit Lantana and Psiguria flowers, but spend most of their time high in the forest canopy.
