ODONATA: Characterisations and their Ecosystem Services

Abstract

Odonata, which includes dragonflies and damselflies, play crucial roles in both terrestrial and aquatic ecosystems, serving as key indicators for biomonitoring and as natural pest controllers. This chapter thoroughly examines the morphological differences between the larvae and adults of the Odonata suborders, Anisoptera (dragonflies) and Zygoptera (damselflies), alongside an investigation into their habitats, locomotion, dietary habits, and respiratory functions. It further explores the diversity across Odonata families and assesses their essential ecosystem services, particularly highlighting their role in sustaining environmental health and aiding in agricultural pest management. By comparing dragonflies and damselflies, this text accentuates their ecological value, especially in terms of environmental monitoring and their effectiveness in managing populations of disease vectors. This analysis aims to illuminate the pivotal role of Odonata in maintaining ecosystem vitality and their beneficial influences on human environments.
