Analis presented in our 85 survey locations that were distributed in all counties on the Taiwan excluded the Taitung county, Hualien county, green island and orchid island. The altitude of P. analis habitats ranged from plain to the 400 m. The eleven types of habitats included bamboo plantation, windbreaks, orchard, dry riverbed, grassland, tea plantation, broadleaf forest, vegetable, paddy field, sugarcane field, and Arecae catechu showed the high diversity. The grassland was found in the highest ratio among 34 habitats and followed by the dry riverbed, which was found eleven sites.
