Seasonal variation in insect biodiversity in a transitioning sub-urban area

Abstract

A survey was carried out on the species diversity of insects in the suburban transition area of ​​Patna. The study was conducted over a one-year period of 2021 (January to December). A total of 41 species of insects have been identified in a small area (10 acre), with Lepidopteran order (20) are dominance over the Hemiptera (5), Hymenoptera (5), coleoptera (4), Odonata (3), and Polydesmida, Mantodea, Diptera, and Orthoptera one species each. All of these species are found based on seasonal variation and vegetation as well as the presence of built-up areas. The highest number of insect species was in September, and the lowest were in May and December. Species of Syntomoides imaon and Mylabris flexuosa were captured during the mating conditions in the months of August and September (rainy season), respectively. These variation indicates the abundance of insect biodiversity and also provides evidence of the abundant food chain of ecosystems.
