Description

<p>Faunal survey of dragonflies and damselflies in the Akasaka Imperial Garden, Tokyo, was conducted during 2012 to 2022, and recorded a total amount of 38 species including some species possibly occasionally came from outside (e.g. Anotogaster sieboldii). Previous study from 2002 to 2004 by Saitô et al., (2005) reported 24 Odonata species from the garden. In comparative with this record, additional 16 species are newly recorded by our survey but two species were not re-observed. Almost all the recorded species are lentic ones. It would be caused by the scarcity of lotic environment in the garden. A total of 12 threatened species ranked in the red list concerned with the biota of Tokyo (Natural Environment Division, Bureau of Environment, Tokyo Metropolitan Government, 2023) is found. This result could be one of rationales for the continued preservation of the Akasaka Imperial Garden, one of precious urban greens in the Tokyo metropolitan area.</p>
