Immature Stages of Teriocolias zelia andina Forbes (Pieridae: Coliadinae)

The egg, larva and pupa of Teriocolias zelia andina Forbes, 1928 (Lepidoptera, Pieridae, Coliadinae) are described and illustrated for the first time based on specimens collected on Senna birostris var. arequipensis (Fabaceae) on the western slopes of the Andes of northern Chile. The morphology of the egg and first instar enables separating T. z. andina from species of its sister genus Leucidia Doubleday, 1847. The larva of T. z. andina passes through five instars, which can be accurately identified by head width.
