Many earlier studies on Thai flora and fauna showed that the richness of the ecosystem in this region
arises from biogeographic situation. The distribution of Lepidoptera species is highly depended
on the distribution of flora, especially food plants. Therefore, by analyzing their distribution
data, we can get some insight into the flora and fauna of this area. Here, we used the Papilionidae
family data. The raw data were composed by 0 or 1 in each cell of the spread sheet according to
the presence or absence in a province. In this analysis, we could analyze the spatial differences and
similarities of provinces from the view point of the butterfly’s distribution. By conducting a factor
analysis with the principal component analysis mode, five factors were obtained. The meanings of
former four factors could be explained. This analytical result seems to support the classification
of zoo-geographical sub-regions proposed by many researchers.
