The Japanese pipistrelle, or Japanese house bat, is a small vesper bat. An adult has a body length of 3.6–4.8 cm, a tail of 2.9–4 cm and a wing length of 3.2–3.6 cm. It prefers to roost under the ceiling or inside the roof of old buildings, and it feeds on beetles, caddisflies, flies, hymenopterans, moths and true bugs (Wikipedia, general species account).
The cached account places it across East Asia, from China and Taiwan into the Ussuri region, Korea and Japan; a mammal-diversity checklist also lists Vietnam. Before a young is born it goes through 33 embryonic stages (Wikipedia, general species account).
