Abstract
Besides serving as important prey and predators in the food chain's
trophic level balance, odonates are important markers of the health of
terrestrial and aquatic ecosystems. The current research endeavors to record
and examine the odonate diversity found in Kerala's Vembanad Lake, a Ramsar
site. Observations were made for a period from November 2022 to May 2024. A
total of 41 species—27 Anisoptera species and 14 Zygoptera species—were
identified, spanning two sub-orders, six families, and thirty genera. The
families obtained were Gomphidae, Libellulidae, Aeshnidae, Chlorocyphidae,
Coenagrionidae and Platycnemididae. Ordre Anisoptera was found to be more
diverse and predominant with 27 species under 24 genera belonging to three
families Libellulidae, Gomphidae, and Aeshnidae contributing 65%, followed by
the order Zygoptera which was less diverse with 14 species under 8 genera
belonging to three families Chlorocyphidae, Coenagrionidae and Platycnemididae,
contributed 34% of total Odonates recorded from the study area. Libellulidae is
the most species-rich family with 25 species, followed by Coenagrionidae, Platycnemididae,
Chlorocyphidae, Aeshnidae, and Gomphidae with 10 species, 3 species, and 1
species respectively. The study will provide baseline information on the
diversity and composition of odonates in the selected study area.
