We describe and illustrate for the first time the third-instar larvae of three Anastrepha species, Anastrepha pickeli Lima, Anastrepha pulchra Stone, and Anastrepha curitis Stone, and also the second instar of A. curitis. Structures such as the cephalopharyngeal skeleton and spiracles are described using optical and scanning electron microscopy. We describe characteristics of the ventral surface of the mandible for the first time for fruit fly larvae.
