Natalus stramineus saturatus, the Mexican funnel-eared bat, actually ranges from Mexico south to Brazil and Bolivia. It is a member of Natalidae, a Neotropical group of aerial insectivores that appear to be specialists in feeding on spiders. All of these bats have funnel-shaped ears and long, slender hind legs. They prefer to roost in hot caves.
