It is hard to guess what a Western false pipistrelle weights. But we have the answer:
An adult Western false pipistrelle (Falsistrellus mackenziei) on average weights 23 grams (0.05 lbs).
The Western false pipistrelle is from the family Vespertilionidae (genus: Falsistrellus). When reaching adult age, they grow up to 88.5 cm (2′ 11″).
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 western false pipistrelle, species Falsistrellus mackenziei, is a vespertilionid bat that occurs in Southwest Australia. The population is declining due to loss of its habitat, old growth in tall eucalypt forest which has largely been clear felled for tree plantations, wheat cultivation and urbanisation. Although it is one of the largest Australian bats of the family, the species was not recorded or described until the early 1960s. A darkly colored bat with reddish brown fur and prominent ears, they fly rapidly around the upper canopy of trees in pursuit of flying insects.
