One study observed that figs were the primary, if not the only, food eaten in all of the study sites. Individuals of this species make frequent flights during the night in search of food. Females in Jalisco, Mexico flew 8 kilometers to forage, approximately thirteen times the distance that females flew on Barro Colorado Island, Panama. Artibeus jamaicencis does not fly in flocks to forage. Instead, each bat arrives at a feeding site, feeds, and departs independently from the others.
Food is carried to night feeding roosts and, towards morning, to regular roosts.
Fruit seeds from bat droppings accumulate under the roosts. Reproduction Throughout its range, the Mexican fruit bat varies in its reproductive stategy. Normal development of the blastocyst resumes in September or November and the young are born in March or April. Gestation lasts about 4 months following the resumption of development of the delayed blastocyst. In Colombia and the Yucatan Peninsula, pregnant females or nursing mothers have been found year-round, suggesting a continuous cycle or acyclic breeding.
