The present study investigates the seasonal dietary composition of Megaderma lyra in the Udaipur region of southern Rajasthan. Fecal samples were collected weekly from beneath bat roosts over one year (2008–2009) at 12 different sites. Prey remains were identified through morphological analysis of these samples, combined with examining culled parts found beneath feeding roosts. Microphotographs were used to confirm the identification of insect parts from the fecal pellets, with insect prey classified up to the order level based on authenticated literature.
