Abstract
A preliminary survey was conducted on the seasonal diversity and
distribution of insect fauna in the Chintamani Kar Bird Sanctuary, West Bengal,
India. The survey was carried out during for one year from May,2025 to April,
2026 field visits representing different climatic seasons. A total of 87
species belonging to 12 insect orders and 49 families were recorded during the
present investigation. The highest abundance of insects was recorded during
summer with 899 (R.A.= 55.76%) individuals followed by monsoon with 586(R.A.=
36.35%) individuals and winter with 127 (R.A.= 7.87%) individuals. Hemiptera
was the dominant order in terms of species richness, while Libellulidae,
Formicidae, Papilionidae, and Nymphalidae were among the most represented
families. Diversity indices revealed higher species diversity during monsoon
season with Shannon diversity index (H') of 3.395 and Simpson index (1-D) of
0.961. Environmental variables such as rainfall, humidity, and temperature
showed positive relationships with species occurrence and abundance. Heat map
analysis also demonstrated distinct seasonal occurrence patterns among insect
species. The present study provides baseline information on the insect
diversity of Chintamani Kar Bird Sanctuary and highlights the ecological
importance of seasonal variation in maintaining insect biodiversity.
