Behaviour and ecology of ;E. mauru s are poorly known. ;In Venezuela, a female was present in a 15-year-old pine (Pinus caribaea ) plantation; original vegetation at this locality corresponds to grass (Trachipoqum ) savannahs, in association with swamps dominated by ;the palm ;Mauritia flexuosa , gallery forests, and swampy evergreen forests (Sanchez et al. ;1992, ;Best ;et al . 2001). In Ecuador, this bat was collected in the tropical evergreen forest (Reid et al . 2000). It is insectivorous; it may feed on large insects as with other species of Eumops .	Because it inhabits lowland forests with a preference for savannah formations and association with palms M. flexuosa , the species could be affected by habitat loss.	This is one of the rarest Neotropical bats; known from a few individuals taken from less than 10 localities in humid lowland areas. It is probably declining through habitat loss. The species is rarely encountered because it is difficult to capture due to its high flying and roosting behaviours (Emmons and Feer 1997).	Decreasing	This bat is known from Brazil, Venezuela, Guyana, Suriname, Ecuador and Peru (Sanchez ;et al . 1992, ;Reid et al.  ;2000, Simmons 2005, Eger 2008, Sodre et al . 2008, Pacheco et al . 2009). It is present at elevations below 500 m (Sanchez et al . 1992, Reid et al . 2000). Most of the localities include lowland Amazonian forests, but at least three correspond to savannah formations in Peru and Brazil.
