Roosts included caves, culverts, hollow trees, holes in trees, and buildings. Both species were netted most often near gardens where bananas were grown. P. hastatus preys on small vertebrates as well as insects, while the diet of P. discolor consists mainly of fruit, pollen, nectar, and insects caught in flowers. The diets of P. elongatus and P. latifolius are not known as well but probably include flower parts, fruits, insects, and small vertebrates such as anoles and geckos gleaned from vegetation. Captive P. discolor are said to feed on fruit and to refuse meat.
Dominant males defend their harems against other males.
P. discolor also occurs in harems, but the females number only 1-12 per dominant male and tend to be more nomadic. The single harem male also sometimes remained for several years, but turnover of male residency was frequent and did not disrupt female social structure. Bachelor male groups, averaging about 17 bats each, were present and were less stable. Resident males repelled intruding males in quick, violent fights but generally ignored female movements. Harem males also hunted separately.
