The lesser bamboo bat (''Tylonycteris pachypus'') is a species of vesper bat in the Vespertilionidae family. It is found in Bangladesh, China, India, Indonesia, Malaysia, Burma, the Philippines and other Southeast Asia countries.〔 The bat, the size of a bumble bee, is among the smallest mammals on earth,〔(Smithsonian Institution )〕 measuring about in length with a wingspan of . It weighs 3.5 to 5.8g, or as little as 2.0g. A 4.8-gram T. pachypus has about a 0.08-g brain. This species lives in the hollow of shoots of the giant bamboo ''Gigantochloa scortechinii''; the entrance slit (created by the Chrysmelid beetle, ''Lasiochila goryi'') to the bamboo tunnel is too restrictive for most predators, such as snakes. Flattened skull (to pass through entryway) and toe and wrist pads (to grip inner surface) are adaptations to their roosting site. Groups of up to 40. Gestation 12 to 13 weeks. Usually two young; female carries young for first couple days, then leaves them behind in bamboo chamber. The young are weaned and become independent at six to seven weeks. Subspecies are: * ''Tylonycteris pachypus aurex'' * ''Tylonycteris pachypus bhaktii'' * ''Tylonycteris pachypus fulvidus'' * ''Tylonycteris pachypus meyeri'' * ''Tylonycteris pachypus pachypus'' ==References== * * * * * (''Tylonycteris pachypus'' in ''Mammal Species of the World'' ) * (China's Tiny Bats ) By Libiao Zhang in Volume 6, Number 9 - September 2008 issue of "Bat Conservation Times". *Mammals of China.
