RESUMO A biologia e morfologia de estágios imaturos de Heliconius sara apseudes (Hübner, [1813]) ainda são pouco conhecidos. Características da morfologia externa dos ovos, larvas e pupa de H. sara apseudes são descritas e ilustradas, utilizando-se microscopias óptica e eletrônica de varredura. Ovos com carenas lisas, larvas de primeiro instar com cerdas contendo projeções escamiformes e larvas do segundo ao quinto instares com corpo apresentando pináculas dispersas são características distintivas de H. sara apseudes em relação às demais espécies de heliconíneos.

ABSTRACT The biology and morphology of the immature stages of Heliconius sara apseudes (Hübner, [1813]) are still little known. External features of the egg, larvae and pupa of H. sara apseudes are described and illustrated, based upon light and scanning electron microscopy. Eggs with smooth carina, first instar larva with scaly setae, and body of second to fifth instars covered with scattered pinnacles distinguish H. sara apseudes from other heliconiine species.

External morphology of the immature stages of Neotropical heliconians: IX. Dione glycera (C. Felder & R. Felder) (Lepidoptera, Nymphalidae, Heliconiinae). The biology of the Andean silverspot butterfly Dione glycera (C. Felder & R. Felder, 1861) is still poorly known. This species is restricted to high elevations in the Andes, where the immature stages are found in close association with species of Passiflora belonging to the section Tacsonia (Juss.) Harms, especially P. tripartida var. mollissima (Kunth), which is grown for subsistence by villagers. Herein we describe and illustrate the external features of the egg, larva and pupa of D. glycera, based on light and scanning electron microscopy.

As estruturas externas do ovo, larva e pupa de Philaethria wernickei (Röber, 1906) são descritas e ilustradas, baseadas em microscopia ótica e eletrônica de varredura.
