Indian Dragonfly (Wandering Glider)

📖 Description

Indian Dragonfly (Pantala flavescens), also called Wandering Glider or Globe Skimmer, is one of the most widespread and important generalist predators in Indian agriculture, found in all agro-ecological zones. The species is remarkable for its long-distance migrations — it undertakes multi-generational migrations across the Indian Ocean between India and Africa, making it one of the longest-distance migrating insects in the world. Both adults and nymphs are voracious predators — adults catch flying insects (mosquitoes, flies, moths, butterflies, leafhoppers, planthoppers) on the wing, while nymphs are aquatic and prey on mosquito larvae and other aquatic insects. A single adult can consume 50-100 prey items per day, with nymphs consuming 20-50 mosquito larvae per day. The species is particularly valuable for IPM of rice pests (leafhoppers, planthoppers, moths) — healthy dragonfly populations in rice ecosystems can suppress pest populations below economic threshold without insecticide use. The species is also culturally significant in India — dragonflies are considered auspicious and are not harmed by farmers. Conservation of native dragonfly populations through maintenance of water sources (ponds, ditches, rice fields), avoidance of insecticide drift to water bodies, and preservation of emergent vegetation around water bodies is essential for sustainable rice IPM. The species is an indicator of healthy aquatic ecosystems — its presence indicates that water bodies are not contaminated with insecticides and that aquatic biodiversity is intact.
