Urban Oasis: 72 Butterfly Species Thrive in Chennai Campus
10 Jan
Summary
- Anna University campus hosts 72 butterfly and moth species.
- Nymphalidae family, the most dominant, comprises 32% of species.
- Butterflies are vital ecological indicators and pollinators.
Within Chennai's urban environment, Anna University's campus has become a sanctuary for 72 species of butterflies and moths. A recent six-month survey conducted by the National Centre for Sustainable Coastal Management documented this rich insect diversity, finding species from 13 families. The Nymphalidae family, known for its adaptability, was the most prevalent, representing 32% of the total recorded abundance.
The presence of diverse flowering plant families, including legumes and citrus, directly supports the flourishing butterfly population. Butterflies are highly sensitive to environmental changes and are critical pollinators, contributing to plant diversity. Their presence signifies a healthy habitat, even within a densely urbanized setting.
While butterflies thrive, moths, particularly from the Erebidae family, show reduced diversity, likely due to habitat loss. This contrast underscores the delicate balance of urban ecosystems and the ongoing need to protect green spaces for biodiversity.
