Rufous Horse-shoe Bat (Rhinolophus rouxii)

Rufous Horseshoe Bat is a common bat occurs from forested parts of the low country to the lower hills (500 m a.s.l) while becoming scarce above 1300 m a.s.l. It roosts day time in caves, old buildings, barns and dark culverts as large colonies of same species or sometime with other species of bats such as Schneider’s leaf-nosed bat (Hipposideros speoris)Long-eared false vampire bat(Megaderma spasma) and Bi-colored leaf-nosed bat (Hipposideros ater). But roosting single individuals or small parties are also not uncommon in such places. It emerges late in the evening from the roosting site and catch small flying insects (Moths, Beetles etc.) by flying about 3-4 feet above the ground below trees or sometime darting at the prey from a perched position in a low bushes. This bat occurs in two color forms,  brown and orange, while later color phase bats are much common during the winter months of the northern hemisphere (Yapa A. & Ratnavira G., 2013).
