This pictorial field guide compiled by ten young naturalists describes 157 species of butterflies recorded in and around Chennai, the capital of the state of the Indian state of Tamil Nadu. The book includes information about butterfly hotspots around the city, fun activities to better interact with butterflies, and keys to distinguish between similar-looking species. The authors of this book have spent more than a few enjoyable afternoons chasing butterflies and hope this guide helps the people of Chennai fill their days the same way.
