The developmental biology and morphological characteristics of the immature stages of Argynnis nerippe were studied in the laboratory using host plant, Viola papilionacea. Dormancy of the first instar larvae was broken when exposed in summer-like conditions (25 ± 1℃ and continuous illumination of 5000-7000 lux). Feeding began within 1-2 days after awakening. This species has six larval stadia and individuals take ca. 60 days (excluding dormancy) to mature from egg to adult. Illustrations and descriptions of the various immature stages and their behaviors are provided.
