The present paper describes the immature stages of the common Neotropical satyrine butterfly Pareuptychia ocirrhoe interjecta (R.F. d'Almeida, 1952). The solitary eggs are white and round, turning black 4 to 6 hours after oviposition. The four solitary larval instars are predominantly green and feed on grasses (Poaceae), including Setaria in nature and several other native and introduced species in captivity. The pupa is short and smooth and entirely green. Except for the black eggs, the immature stages are similar to those of other forest species of Euptychiina. The most remarkable and unique characteristic of P. ocirrhoe interjecta is the shiny black eggs, a possible synapomorphy for Pareuptychia not known in any other Euptychiina.
