According to Mrs. Rutkowski, these three bats (Wahlberg's epauleted bat, the Honduran white, and the gray-headed flying fox) are good examples of megabats (UPDATE: it turns out that the Honduran white is NOT a megabat. But I'll leave it here to the comments make sense).

What's a megabat? The name itself can be a bit misleading, as the smallest of this group is only about 2.4 inches long. In general, they're fruit eaters and nectar lickers. They don't use echolocation (except for an Egyptian species). This is all in contrast to microbats, who tend to use echolocation and eat insects.
Of course, no where in the line up is the draculabat. I think we may have a certain Transylvanian editing Wikipedia for his own purposes.
