What is the maximal age a Brown long-eared bat reaches?
An adult Brown long-eared bat (Plecotus auritus) usually gets as old as 30 years.
Brown long-eared bats are around 65 days in the womb of their mother. When born, they weight 2 grams (0 lbs) and measure 4.6 cm (0′ 2″). As a member of the Vespertilionidae family (genus: Plecotus), a Brown long-eared bat caries out around 1 little ones per pregnancy, which happens around 1 times a year. Fully grown, they reach a bodylength of 30 cm (1′ 0″).

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.

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.
