The long-legged bat (Macrophyllum macrophyllum) is a bat species from South and Central America. It is monotypic in its genus.[2]
It hunts close over the water surfaces of lakes and slowly flowing streams, where it seizes insects right above or directly off the surface in a manner similar to Noctilio leporinus and Myotis daubentoni. This is an interesting example of convergent evolution, which may imply just how valuable a habitat the water surface is to insectivorous bats.
The sound emission in contrast is quite different from other water-hunting bats. M. macrophyllum has a very prominent noseleaf, and it emits the echolocation sounds through the nostrils. The time frequency characteristics of the sounds are almost identical to those of Micronycteris microtis: short (1-2 ms) multiharmonic FM sweeps with most energy in the second harmonic between 95 and 75 kHz. However, the sounds resemble those of a number of other phyllostomid bats, including Micronycteris microtis, but new results indicate that the intensity is significantly higher.
