 They may change roosts daily however (when food was available) distances between subsequent roosts in NSW were short (average 42m at Iluka or 125m at Harrington).They are probably important pollinators, as they carry six times as much pollen as birds while also traveling further in a night.The bumpy satinash tree is an important food source for this species in North Queensland, as 95% of all pollen observed on their fur comes from this species on bats caught near flowering trees.
