From February 1996 to January 1997, a primary survey and study for the topics of distributions, periods of adult’s appearance, characteristics of habitat environment and the possible problem while working on recovery of fire-flies was conducted on all five National Parks of Taiwan area and the Kin Men National Park, Fu Jien Province. One or two points or trails of landscape were chosen as the regular location of investigation of each national park under limited conditions. All activities of investigation were conducted on night-time and took a looking for both adults and larvae by netting or picking and bring collections back to indoor for further rearing, observation and identification. According to the materials so far, at least 12 species of fire-fly distributed in Yu Shan National Park, 11 species in Shei Pa National Park, 8 species in Yang Ming Shan National Park, 6 species in Ta Ro Ko National Park, 4 species in Ken Ting National Park and 2 species in Kin Men National Park. Not including the species of distributing over two or more National Park, there are totally 13 species of fire-fly being recorded currectly in all six National Parks. This text contains a brief researching history on Taiwan and in the world, the ecology, a introduction to the mechanism of light production, causes of population decreasing and the Taiwanese name-list of fire-fly, and the future executing overviews of recovery plan. Meanwhile, the experiences of Japanese recovery of fire-fly are reported which might be the references of fire-fly recovery of Taiwan in order to make a appropriate construction and planning depending on the different environmental characteristics of each Parks.
