abstract
The present investigation on species diversity and abundance of butterfly was carried out in and around, CUTM, Paralakhemundi campus during January-2017 to June-2018. A total of 578 individuals butterfly were recorded during the present study. Out of which, 45 species under 5 families viz., Papilionidae, Nymphalidae, Pieridae, Lycaenidae and Hesperiidae were observed. The highest number was recorded from family Nymphalidae (22 species, 48.89%) followed by Pieridae and Lycaenidae (7 species each with 15.56%) however, Papilionidae and Hesperiidae recorded 5 and 4 species with 11.11 and 8.89% of relative abundance, respectively. Out of 45 species, 44 were found in forest ecosystem with total abundance of n= 299 followed by 35 species (n=153) in horticultural ecosystem and then 33 species (n=126) in agro- ecosystem. The forest ecosystem recorded the highest diversity index and evenness (3.59 and 0.95) followed by agro-ecosystem (3.24 and 0.93) and horticultural ecosystem (3.23 and 0.91). The highest number of species was recorded from forest ecosystem and the presence of such diversity in and around the campus reflects the healthiness of the surrounding environment.
