Heliconius xanthoclesMargarita Beltrán and Andrew V. Z. Brower
Early stages: Eggs are yellow and approximately 1.1 x 0.9 mm (h x w). Females gather together and usually each place 10 to 40 eggs on growing shoots and tendrils of the host plant. Early instar larvae have a yellow body with black bands. Mature larvae have black scoli and head, length is approximately 0.3 cm. Caterpillars are gregarious (Brown, 1981).
Adult: Heliconius xanthocles adults can be distinguished from other Heliconius species by the presence of yellow scales on the edges of the abdominal segments, giving the abdomen a ringed appearance. The wing patterns exhibit a high degree of geographical polymorphism. Several races from northern South America have entirely black hindwings, and one from southeastern Colombia (H. xanthocles explicata Brown 1976) has almost no red on either forewing or hindwing.
Heliconius xanthocles is distributed in the Amazon basin. This map 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
H. xanthocles occurs from sea level to 1,500 m in marginal forest. Usually individuals fly rapidly and in the canopy.
Hostplant: H. xanthocles larvae feed primarily on Passiflora from the subgenus Granadilla, from Simplicifoliae, Lobatae, and Kermesinae sections. The secondary natural food plants are Quadrangulares/Digitales/Laurifoliae and Menispermifoliae/Setaceae/Pedateae/imbricatae/Incarnatae sections (Brown, 1981).
