Fig. 1. Maps of the Urato Islands and vegetation classification. Eight communities were considered when the Katsura and Sabusawa Islands were divided into two and three areas, respectively, as shown by the black lines. 1, residential areas, roads, and other man-made structures; 2, rice fields; 3, other crop fields; 4, grasslands with vegetation

Fig. 2. Relationship between the dissimilarities between butterfly communities and host plant communities (a), dissimilarities between butterfly communities and geographic distance (b), and dissimilarities between host plant communities and geographic distance (c). The r and P values shown in the figures were obtained by the Mantel test. Dissimilarities in relative species abundance of butterfly and relative resource abundance were calculated by using Odum's percentage difference method. The results for five-community analysis are shown in SI Fig. 5.
