The immature stages of Caligopsis seleucida (Hewitson, 1877) are described from laboratory studies conducted in Diamantino (Mato Grosso) and Contagem (Minas Gerais). The larvae reared in Mato Grosso fed on Phyllostachys aurea A. & C. Rivieri and Dendrocalanus giganteus Munro (Poaceae), while the other larvae fed on P. aurea and Bambusa vulgaris Schrad. (Poaceae). The ontogenetic development from egg to adult emergence (in Mato Grosso) lasts 115 days when the larvae pass through five instars, and 147 days when there is an extraordinary larval instar. Immatures and adults are illustrated in color.
