External morphology of the immature stages of Neotropical heliconians: X. Heliconius sara apseudes (Lepidoptera, Nymphalidae, Heliconiinae)

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.
