Pteropus seychellensis comorensis is the only Pteropodidae bat species on the island of Mayotte (Comoros Archipelago), and most aspects of its biology are unknown. In order to catch this large bat, we used a simple and low-cost method, consisting of raised mist nets that were set close to foraging sites. Major factors driving catch success were high food availability, good positioning of mist nets, and careful observation of movement patterns to identify foraging sites where the chances of capture are high. Blood was collected from the alar and humeral veins, which appear to be more practical for this purpose than other parts of the venous system.
