The Study of Diversity of Odonata (Dragonflies and Damselflies) Fauna of Angod Village, District- Uttara Kannada, India

Abstract

Purpose: The purpose of this checklist is to provide comprehensive documentation of dragonfly and damselfly species observed in the study area, thereby contributing to the existing biodiversity records. It aims to facilitate understanding of species distribution and abundance, which is crucial for informing conservation efforts and habitat management. Additionally, this checklist serves as a baseline for future ecological research and monitoring programs, enabling comparisons over time. It acts as a valuable resource for educators, researchers, and enthusiasts in the study of Odonata, while also enhancing taxonomic clarity and supporting accurate species identification within the region.

Methodology: During June and July 2021, field surveys were conducted to observe dragonflies and damselflies using the Pollard Walk Method (PWM), with observations made twice daily—once in the morning from 7:00 am to 8:00 am and again in the evening from 5:00 pm to 7:00 pm-targeting their peak activity periods. No specimens were collected or disturbed, and individuals that were challenging to identify in the field were photographed or observed carefully until sufficient data were gathered, adhering to ethical guidelines and ensuring minimal impact on the species and their habitats.

Results & Findings: The survey in Angod recorded 14 species of dragonflies and 5 species of damselflies, demonstrating the region’s odonate diversity. Dragonflies were predominantly observed near open water sources such as ponds, streams, and agricultural fields, while damselflies favoured more shaded areas with dense vegetation near still water bodies. The survey found that dragonflies were generally more adaptable to a variety of habitats, whereas damselflies exhibited specific preferences for calm, undisturbed waters. This variation in habitat selection suggests different ecological roles played by dragonflies and damselflies in the local ecosystem. The presence of these species highlights the richness of the Western Ghats and underscores the importance of protecting aquatic habitats to maintain biodiversity.

Originality/Value: This research offers a unique contribution to the study of dragonfly and damselfly diversity in the relatively unexplored region of Angod, located within the Western Ghats of India, a biodiversity hotspot. Unlike previous studies that often focus on more widely surveyed regions, this study provides the first detailed documentation of odonate species in Angod. The methodology, involving non-invasive photographic documentation during key activity periods, ensures minimal disturbance to the species and their habitats.

Type of Paper: Survey-based exploratory research.
