Eggs, fifth instar larvae and pupae of A. dubia (Boheman, 1854), A. fuscata (Klug, 1829), A. languida (Boheman, 1854), A. phaeopoda Buzzi, 1976 and A. punctulata (Klug, 1829) are described. Imatures stages were reared in a stove Biometron under temperature of 25±2ºC, photophase of 12 hours and relative humidity of 80±5%. The larvae of A. dubia and A. languida were fed with leaves of Baccharis relusa DC; A. fuscata with leaves of Baccharidastrum argutum (Less) Cabrera; A. phaeopoda with leaves of Baccharis gaudichaudiana DC. and larvae of A. punctulata with leaves of Baccharis trimera (Less) A. DC.. All plants belonging to the Asteraceae.
