ResumoEven though it is abundant throughout its distribution range, Myotis levis (I. Geoffroy, 1824) is a poorly-known species. Field efforts were carried out in the present study to better understand some aspects of this species natural history on the shelter (house shelter). Information was obtained through captures using mist-nets positioned at the exit of an artificial shelter, during three consecutive nights, as well as incursions into the shelter, with the goal of estimating the number of individuals in the colony. The study area is located within the Palmas Grasslands, Palmas Municipality, southern Parana (26o34’59”S and 51o36’16”W). Captures resulted in 186 individuals, being 96 adults and 90 juveniles. The colony size was estimated in circa of 12 000 and 15 000 individuals. Based on the structure of the population, the presence of reproductive females, juveniles, and infants, a nursery colony was characterized. In addition to aspects of their reproductive biology, this study deals also morphometric and coloration variations, as well as two cases of partial albinism.
