Description:	ABSTRACT. The goal of this study was to detail the temporal and morphological parameters of the immature stages of Spodoptera cosmioides (Walker, 1858) and to gather information about their larval host plants. Larvae were reared on artificial diet and under controlled conditions (25 ± 1°C, 70 ± 10% RH and 14 hour photophase). The viability of eggs, larvae (pre-pupae period inclusive) and pupae were 98.97, 97.33, 97.95 and 94.76%, respectively. The average duration of egg, larval, pre-pupal and pupal stages was 3.82, 19.24, 3.20 and 14.81 days, respectively. A small proportion of females (9.48%) passed through seven instars, and female development was significantly slower than male development. The female larvae that developed through six and seven instars exhibited a mean growth rate of 1.63 and 1.49, respectively. Overall, female pupae were significantly larger, exhibiting slower development than males. One hundred and twenty six plants belonging to 40 families are listed as hosts of S. cosmioides, mainly including Solanaceae, Fabaceae, Asteraceae and Poaceae.
