Immature Stages and New Host Plant Records for Three Species in the “Taygetis Clade” of Euptychiina in Southeastern Peru (Lepidoptera: Nymphalidae: Satyrinae)

We report here the immature stages and natural host plants for three species in the so-called “Taygetis clade” of the nymphalid butterfly subtribe Euptychiina, Taygetis echo (Cramer, 1775), Taygetis sosis Hopffer, 1874, and Pseudodebis valentina (Cramer, 1779). The study was carried out at Finca Las Piedras in Madre de Dios department, Peru. Taygetis echo was observed utilizing a species of herbaceous bamboo, Olyra latifolia L. (Poaceae: Bambusoideae: Olyreae), T. sosis was found feeding on another species of herbaceous bamboo, Pariana lunata Nees (Poaceae: Bambusoideae: Olyreae), and P. valentina was found utilizing a species of woody bamboo, Guadua weberbaueri Pilg. (Poaceae: Bambusoideae: Bambuseae). We describe and provide photos of the immatures and host plants, as well as illustrations of the head capsules for each of these three species.
