Abstract
 Anax nigrofasciatus nigrofasciatus is a common species of dragonflies that appear even on the urban waterside. This dragonfly is considered as the index species for developing of waterside biotopes. However, the life cycle such as eclosion period and frequency of visiting has not been well studied yet.
 For the purpose of utilizing the understanding about the life cycle of the dragonfly to the planning of future waterside biotope, we carried out the surveys on eclosion and frequency of visiting of Anax nigrofasciatus nigrofasciatus in the biotope of PENTA-OCEAN CNSTRUCTION Institute of Technology. The live camera is also utilized for the investigation of the frequency of visiting. As the result, it was possible to understand the eclosion population and visiting frequency of the dragonfly.
