Animal Weight

How much does a Java pipistrelle weight?

It is hard to guess what a Java pipistrelle weights. But we have the answer:

An adult Java pipistrelle (Pipistrellus javanicus) on average weights 4 grams (0.01 lbs).

The Java pipistrelle is from the family Vespertilionidae (genus: Pipistrellus). When reaching adult age, they grow up to 12.18 meter (40′ 0″). Usually, Java pipistrelles have 2 babies per litter.

As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.

The Java pipistrelle (Pipistrellus javanicus) is a species of pipistrelle bat found in South and Southeast Asia, including Afghanistan; Bangladesh; Brunei; Cambodia; China; India; Indonesia; Laos; Malaysia; Myanmar; Nepal; Pakistan; Philippines; Singapore; Thailand and Vietnam. It favors human habitations. A 2010 research paper from the Philippines regarding the prevalence of coronavirus in bats tested several Java pipistrelle bats.
