Abstract

A list of 55 butterfly species recorded in Shikoku Research Center (SRC), Forestry and Forest Products Research Institute, Kochi City, southwestern Japan from1991 to 2012 has been compiled from collection data. It consists of eight papilionid, six pierid, 13 lycaenid, 22 nymphalid and six hesperiid species. One of these species, Acytolepis puspa, is thought to have invaded SRC as early as the late 1990's. Another species, Chilades pandava, is a stray species which was recorded at many places of Kochi Prefecture in 2009-2010. According to Tanaka's criterion, excluding C. pandava, there are 37 forest species and 17 grassland species at the study site. The Sunose environmental index (EI) based on the 54 species recorded in the 1991-2012 period was 105, which indicated a "good natural environment". The EI value based on the species recorded in 2006-2012 was 96, indicating that the present environmental condition of SRC is of a moderate level. The ratios of Himalayan (14.8%) and Malayan (20.4%) geographical distribution-type species in SRC were higher than the national average in Japan. Eurema laeta, Artopoetes pryeri and Damora sagana, Red Data species of Japan and/or Kochi Prefecture, were recorded in the early 1990's, but E. laeta and A. pryeri have not been observed in the 2000's.
