Northern little yellow-eared bat

The northern little yellow-eared bat, Vampyressa thyone, is a bat species with a long north to south range, found from southern Mexico to Bolivia, the Guianas and western Brazil. It was described by Oldfield Thomas in 1909 and belongs to the genus Vampyressa. The English Wikipedia article is a short stub that gives its range and naming authority and says nothing about its habitat, diet, behaviour or numbers, so none of those are claimed here.
