Species Diversity And Seasonal Variations Of Butterflies (Lepidoptera) In Thoothukudi And Tirunelveli Districts, Tamil Nadu

Abstract

Butterflies are an important group of insects that serve as ecological indicators and play a key role in pollination. The present study focuses on the species diversity and seasonal variations of butterflies in the Thoothukudi and Tirunelveli districts of Tamil Nadu, India. Over the course of one year, monthly surveys were conducted across various habitats, including agricultural fields, forests, and urban areas. A total of 80 butterfly species were recorded across five families, with the highest species diversity observed during the monsoon season. The research findings highlight the seasonal fluctuations in butterfly populations and emphasize the importance of habitat conservation for maintaining these vital species in the region.
