Southern long-nosed bats spend the day roosting in caves and abandoned mines, often shared with a number of other bat species. They are highly gregarious, with colonies numbering in the thousands of individuals. They are agile fliers, feeding on nectar,
pollen, and fruit. For most of the year, around 90% of their diet is derived from various species of
cactus, although they also feed on
Agave and
Ceiba when those plants are in bloom. They have been identified as important
pollinators of local cacti. Breeding takes place between November and December, and births in May. The young are born and raised in a limited number of maternity caves, often located on islands. The young are weaned at around two months, and the bats live for up to ten years. ==References==
