Diurnal variation in the activities of three common Odonate species at their natural habitat
Keywords:
Aethriamanta brevipennis, Ceriagrion coromandelianum, Diplacodes nebulosa, odonataAbstract
Odonata is a common insect order of India which acts as a bioindicator of the wetland ecosystem. Both Dragon and Damsel fly exhibit diurnal variation of their activity which is related to environmental thermal intensity. The flier Dragon fly species Aethriamanta brevipennis (Family: Libellulidae), Diplacodes nebulosa (Family: Libellulidae) and percher Damsel fly species Ceriagrion coromandelianum (Family: Coenagrionidae) exhibited differential activity patterns adjacent to a wetland. Flying activities were more pronounced at morning and territoriality was more observed at afternoon especially by D. nebulosa. The percher species C. coromandelianum spent more time in resting.
