Aero-net and visual count were used to survey the butterflies, and the indices of family richness were 0.0462 in the Papilionidae, 0.6458 in the Pieridae, 0.0076 in the Danaidae, 0.0537 in the Nymphalidae, 0.0158 in the Satyridae, 0.2296 in the Lycaenidae and 0.0011 in the Hesperiidae. Among the 7 families, the appearance frequency of Pieridae was the highest. March and April 2003 ranked first and second, respectively, with 22 and 20 species of species of butterflies recorded. February 2003 ranked first, with 517 counts in terms of numbers of butterflies sighted. Butterflies were collected using moth traps form January 2002 to April 2003. The Pieridae, Nymphalidae and Satyridae had rates of trapping of 1.87 %, 8.61 %, and 89.51 % respectively. The rate of trapping of Satyridae was the highest. March and May 2003 ranked first and second, respectively, in terms of species and numbers of butterflies trapped with 12 families 50 counts and 10 families 39 counts. Pieris rapae crucivora, Zizeeria maha okinawana, Pieris canidia canidia, Catopsilia pomona pomona, Eurema hecabe hobsoni and Melanitis phedima polishana were the most-common species."
