Female Northern Broad-nosed Bats are larger than the males.
Northern Broad-nosed Bats roost in hollows in old trees and occasionally in small gaps in houses, sheds and other buildings. They roost together in small colonies, though when roosting in houses the colonies can be large and smelly.
Feeding and diet
Small flying insects such as midges, mosquitoes and mayflies. They fly quickly, diving and twisting as they chase and catch their prey in flight.
Northern Broad-nosed Bats are vulnerable to loss of roost sites in tree hollows and loss of feeding grounds by forestry activities, clearing for agriculture and housing.
