Queen Mary’s College is not only known for its rich culture and heritage, it is in a 17-acre campus with lush green trees and abundant fauna which makes the campus known for its rich biodiversity. The rich flora attracts more butterflies to our campus. Around 82 different species of butterflies are spotted in the campus throughout the year. Some butterflies are seasonal and some are migrants. The entire campus has good number of host plants like Ashoka, Curry leaves, Lime, Nerium, Castor, Buttercup and nectarine plants like Ixora, Lantana, Tridax etc. These host and nectarine plants attract butterflies such as Common Crow, Common Castor, Crimson rose, Common Mormon, Dark Grass Blue, Lime Butterfly and so on. Students are encouraged to study the diversity of butterflies and record their life cycles. This motivates them to pursue research on Butterfly Diversity and to study their behaviour patterns and host plant interactions. Outreach activities were organized for school and college students on the Conservation and protection of Butterflies.
