How much does a Serotine bat weight?

It is hard to guess what a Serotine bat weights. But we have the answer:

An adult Serotine bat (Eptesicus serotinus) on average weights 23 grams (0.05 lbs).

The Serotine bat is from the family Vespertilionidae (genus: Eptesicus). It is usually born with about 5 grams (0.01 lbs). They can live for up to 6 years. When reaching adult age, they grow up to 6.8 cm (0′ 3″). On average, Serotine bats can have babies 1 times per year with a litter size of 1.

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 average adult weight of a Serotine bat is 23 grams (0.05 lbs)

The serotine bat (Eptesicus serotinus), also known as the common serotine bat, big brown bat, or silky bat, is a fairly large Eurasian bat with quite large ears. It has a wingspan of around 37 cm (15 in) and often hunts in woodland. It sometimes roosts in buildings, hanging upside down, in small groups or individually. The name serotine is derived from the Latin serotinus which means “evening”, while the generic name derives from the Greek ἔπιεν and οίκος which means “house flyer”.
