GS-III (Environment and biodiversity): mass insect migrations signal ecosystem health and the connectivity of habitats between the Eastern and Western Ghats. Threats such as habitat fragmentation, pesticide use and climate-driven changes in monsoon timing affect pollinators and migratory corridors. The way forward lies in protecting corridors, regulating pesticide use, long-term monitoring (including citizen science) and integrating insects into conservation planning under the Wildlife (Protection) Act and biodiversity-hotspot management.
