Abstract
Xitou nature education center is one of the NTU experimental forests in Nantou County, and also a famous recreation area in central Taiwan. In every April, the firefly-watching is the main event of fireflies’ ecotourism in every April in Xitou area. However, the biological censuses in Xitou area are limited to flora and fauna except fireflies. In this investigation, qualitative and quantitative surveys, including sweeping net, trap collection (flight interception trap and SLAM trap), transect sampling and marking-release-recapture method were conducted for realizing the community components and seasonal dynamics of fireflies in Xitou area. From January 2011 to April 2012, six sampling sites were selected：Conifer Specimen Park (CSP)、CO2 Flux Tower (CFT)、University Pond (UPO), University Pit (UPI), Mt. Fenghuang Ridge (MFR), and Store Street (SS). 1.797 fireflies of 11 genera and 29 species were collected, including several new recorded species:, Cyphonocerus sangunineus Pic, Diaphanes formosus Olivier, Drilaster purpureicollis Pic, Drilaster sp.1, Drilaster sp.2, Cyphonocerus sp., Drilaster sp.3. The species numbers of Lampyridae were 33 in Xitou area. Site MFR had the most fireflies’ species, where as Sites UPO and CFT had fewest. In Xitou area, the most abundance of fireflies occur from April to July and from October to December. The dominant species are Luciola cerata Olivier in spring and Diaphanes lampyroides Olivier in winter, and the suitable fireflies observation sites are at site CSP and UPI. This investigation could be used for maintaining quality of firefly watching and conserving firefly resource. An integrated management strategy, including science education, reducing human interference and suggestion for firefly watching are mentioned.
