  The adult butterflies were collected from ten localities of Distt. Bagh through out the year 1998. A total of 27 species belonging to 5 families and 15 genera were collected. Diversity was calculated by using Shannon-Wiener`s diversity index, Shannon`s equitability, Margalef`s index, Simpson`s index and RI index. The calculated values showed that diversity was slightly higher at Sudhan Gali and Mang Bajri, where as it was lower at Naumanpura. None of the reported species was found to be threatened to become extinct or found to be favored by enriched flora.

  The cannibalistic behaviour of various developmental stages of Coccinella septempunctata was investigated on scarcity of food and different degrees of hungerness. There was an indiscriminate egg cannibalism among the larvae and adults of their own and on the eggs of other species i.e. Menochilus sexmaculatus, Adalia bipunctata, Adonia variegata. The scarcity of food was not absolute reason for cannibalism. In both developmental stages (larvae and adult) kin recognition ability was also poorly proved. The fourth instar larvae were seemed more voracious while feeding on eggs as well on the 1st instar larvae as compared to other three instars. The increasing numbers of egg consumption by adults was also related to their egg production and total number of oviposition days. It is concluded that cannibalism increased the survivorship and shortened the developmental period.
