New Host Plant Records for Ragadia luzonia and Acrophtalmia yamashitai (Lepidoptera: Nymphalidae: Satyrinae) from Negros Island, Philippines, with a Summary of Spike Moss-Feeding Butterflies.

A new larval host plant, Selaginella engleri (Selaginellaceae), is recorded for both Ragadia luzonia negrosensis Yamaguchi & Aoki, 1982 and Acrophtalmia yamashitai yamashitai Uémura & Yamaguchi, 1982 from Negros Island, Philippines. The egg and first larval instar are described and illustrated. Other butterflies using Selaginella spike mosses as larval host plants are also listed and discussed. [ABSTRACT FROM AUTHOR]
