Scarabaeid beetles constitute an ecologically significant component of terrestrial ecosystems, yet their functional roles within rapidly urbanizing landscapes remain insufficiently documented. This study investigates the ecological roles of Coprophagous and Phytophagous Scarabaeid beetles across diverse habitats within the Pune District of Maharashtra, India. Systematic sampling was conducted in agricultural fields, grasslands, forest fragments, and peri-urban zones to assess species composition, abundance, and functional contributions. Coprophagous species were found to enhance soil nutrient cycling, facilitate organic matter breakdown, and support secondary seed dispersal, thereby improving soil structure and fertility. In contrast, phytophagous Scarabaeid beetles played dual roles: while contributing to plant litter removal and nutrient turnover, some species exhibited herbivory that influenced local vegetation dynamics. Spatiotemporal analyses revealed that land-use patterns, microclimatic conditions, and resource availability strongly shaped beetle community structure, with a noticeable decline in functional diversity in heavily modified landscapes. Overall, the findings highlight the indispensable roles of Scarabaeid beetles in sustaining soil health, regulating nutrient cycles, and maintaining ecosystem stability around the Pune District. The study underscores the need for habitatsensitive conservation strategies to preserve these functionally important insect guilds amidst increasing anthropogenic pressures.
