| Larval development of Nannopaya pygmaea Rambur (Libellulidae), an endangered dragonfly in Korea, was studied using an introduced lariat population in an artificial wetland habitat. Artificial habitat was created in a green house which imitated a small wetland in Boryeong-si, Chungcheongnam-do, Korea, where N. pygmaea inhabited. A total of 300 N. pygmaea larvae were introduced to the artificial habitat in June 2007. Larvae were recaptured five times between June 2007 and November 2008 for measurement of body length. As a result, the initial and recaptured populations (Recaptured I, II, III, IV, and V populations, respectively) contained two body size groups [initial 6.20$pm$0.34 mm and 7.94$pm$0.46 mm (mean$pm$SD); Recaptured I 2.84$pm$0.43 mm and 5.16$pm$0.83 mm; Recaptured II 5.96$pm$0.66 mm and 8.02$pm$0.35 mm; Recaptured III 5.97$pm$0.73 mm and 7.82$pm$0.37 mm; Recaptured IV 7.04$pm$0.93 mm and 8.52$pm$0.39 mm; Recaptured V 5.72$pm$0.60 mm and 7.71$pm$0.30 mm]. Our rearing experiment evidenced that the recaptured I-V populations are the offspring of the initial population and the offspring grew approximately 3 mm at 470 degree days. It was also estimated that N. pygmaea larvae need approximately 100 degree days to grow 0.7 mm in body length. |
