Abstract
Butterflies are not only beautiful creatures but do a great deal for the environment. Like bees, they are plant pollinators, and they provide population control for a number of plant and even insect species by eating them. They also serve as sustenance for other species. A study to find out the diversity and richness of butterflies at the Govt. Science P.G. College Rewa, India was carried out over a period of two years from 2021 to 2022. A total 38 butterfly species belonging to 5 families and 01 order. The maximum number of species belong to family Nymphal idea with 15 species, Lucanidae with 08 species, Pieridine with 07 species, Papilionoidea with 05 species, and minimum number of 03 species Hesperides. Out of 38 species Eurema hecabe was the most dominate species followed by Talicada nyseus and Catopsilia pyranthe. The most abundant species are Eurema he Cabe (with 74 individual) followed by Talicia nisus (with 34 individual) and Catonsville pyran the (with 24 individual). Diversity and richness of butterfly species were calculated during the course of study which were H=2.401 and 5.664 respectively. Dominance of the species can be explained by the presence of their larval form and host plants in the college campus.
