It is hard to guess what a Brown long-eared bat weights. But we have the answer:
An adult Brown long-eared bat (Plecotus auritus) on average weights 8 grams (0.02 lbs).
The Brown long-eared bat is from the family Vespertilionidae (genus: Plecotus). It is usually born with about 2 grams (0 lbs). They can live for up to 30 years. When reaching adult age, they grow up to 8.1 cm (0′ 4″). On average, Brown long-eared 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 brown long-eared bat or common long-eared bat (Plecotus auritus) is a small Eurasian insectivorous bat. It has distinctive ears, long and with a distinctive fold. It is extremely similar to the much rarer grey long-eared bat which was only validated as a distinct species in the 1960s.An adult brown long-eared bat has a body length of 4.5-4.8 cm, a tail of 4.1-4.6 cm, and a forearm length of 4-4.2 cm. The ears are 3.3-3.9 cm in length, and readily distinguish the long-eared bats from most other bat species.They are relatively slow flyers compared to other bat species.
