A total of 900 specimens were recorded, 19 species were identified belonging to 10 genera.

Seasonal distribution of nymphalid butterfly populations were highest (22.11%) in spring and lowest (12.22%) was found in autumn season. Ten species were found almost all seasons and rest of the 9 species was seasonal. Among the identified species, Junonia almana and Junonia atliteswere found most abundant species in this study areas and their relative abundance (RA) was 30.44% for J. almana and 22.56% for J. atlites.
