摘要: Abstract We conducted a field study in September 2007 and 2008 to analyze the foraging activity, natural diets, predatory efficacy of Tetragnatha javana (Thorell 1890) (Araneae: Tetragnathidae) Neoscona theis (Walckenaer 1842) Araneidae) on selected prey. The relationship between body measurements (carapace width, leg length, total weight) web dimensions (capture area, capture thread number radii, spirals, mesh height) both species was also investigated. Most observed T. constructed their webs two adjacent rice plants, while N. placed theirs at top plants. Both required approximately an hour complete web, which differed significantly from each other height, diameter, area. only single per day. Web building activity intense 17:00 18:00, prey-handling high 19:00 20:00. In species,...
