Abstract
A survey on moth diversity (Lepidoptera: Heterocera) in and around the
Bongaon region of the Khumtai revenue circle, Golaghat district, Assam, India
Abstract: Assam's diverse environments, which include grasslands, tropical
forests, and wetlands, contribute to its immense biodiversity, which includes a
broad spectrum of moth species. The present study examines the species richness
and diversity of the moth fauna of the Bongaon region in the Khumtai Revenue
Circle, Golaghat district of Assam, and gives a comprehensive list of all
documented families. The survey was carried out between March 2021 and February
2022 using a light-sheet system and a light trap. During the study, 2277
individuals of 36 species belonging to 10 families and 34 genera were recorded.
Based on the number of species, the family Erebidae was the most dominant at
40.6% followed by Noctuidae at 18.5%, Geometridae at 13.3%, Pyralidae at 6.11%,
Zygaenidae with 4.92%, both Limacodidae and Pyrausdtidae each 4.75%, Crambidae
4.04%, Notodontidae 1.54% and Nolidae 1.45 each. The Shannon-Weiner index
(Shannon H') indicated overall a higher moth diversity (3.39) in the study area
with a seasonal higher diversity value (3.45) during pre-monsoon and least
during retreating monsson (3.30). Again, increased values of the Simpson's
Reciprocal Diversity Index imply increased biodiversity; however, the Simpson's
Diversity (D) value is low in all the sites, indicating high community
diversity. Based on the evenness index (J), it is found that all the study
sites possess nearly even distribution (0.92-0.96) and dispersal of species
that further emphasizes on their conservation importance.
