The present study was carried out to investigate the insect faunal diversity and habitat-wise distribution of some insect orders in Dimbhe Dam and its surrounding area in Maharashtra. Insects are the most abundant and diverse group of organisms and play an important role in ecological balance as pollinators, predators, decomposers and bio-indicators of environmental health. The survey was conducted in three different habitats namely agricultural area, plant-rich area and residential area to understand the effect of habitat variation on insect diversity. The study was performed using photographic documentation during morning and evening hours, and insects were identified up to order and family level using standard identification guides. During the study, insects belonging to three orders — Lepidoptera, Hemiptera and Odonata — were recorded from all three sites. The results showed that insect distribution varied according to habitat conditions such as vegetation, moisture, availability of food and human disturbance. Residential area showed highest number of Lepidoptera due to artificial light and garden plants, while Odonata were more abundant in agricultural and plant-rich areas because of the presence of water and moist environment required for breeding. Hemiptera were found in all habitats showing wide adaptability. The study indicates that habitat type strongly affects insect diversity and provides baseline information useful for biodiversity assessment and conservation planning in the Dimbhe region.
