Heliconius hecalesiaMargarita Beltrán
Early stages: Eggs are yellow and approximately 1.2 x 0.8 mm (h x w). Females usually place 2 to 10 eggs on growing shoots of the host plant. Mature larvae have a dark green to brown body with long black spines, and black head; length is around 1 cm. Caterpillars are gregarious (Brown, 1981; DeVries, 1997). Pupae are slate grey with black markings, the thorax is strongly bowed and have short abdominal spines. The head has long head horns and the antennae have many short black spines (DeVries, 1997).
Adult: In Costa Rica H. hecalesia formosus is distinguished from its comimics hecale and Tithorea tarracina by the black hindwing apex, which has a row of spots within it, and a rounded forwing apex. Forewing length: 45-48 mm (DeVries, 1997).
Heliconius hecalesia is distributed from Central America to Venezuela and Ecuador. 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.
H. hecalesia occurs from sea level to 1,700 m in steep forests. Usually individuals fly rapidly and in the canopy. 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 to 10 m above ground in twigs or tendrils (Brown, 1981).
Host plant: H. hecalesia larvae feed primarily on plants from the subgenera Tryphostemmatoides and Plectostemma (Passifloraceae) (Brown1981). In Costa Rica they utilize Passiflora biflora and P. lancearea (DeVries, 1997).
