How old does a Serotine bat get? (age expectancy)

What is the maximal age a Serotine bat reaches?

An adult Serotine bat (Eptesicus serotinus) usually gets as old as 6 years.

Serotine bats are around 65 days in the womb of their mother. When born, they weight 5 grams (0.01 lbs) and measure 8 cm (0′ 4″). As a member of the Vespertilionidae family (genus: Eptesicus), a Serotine bat caries out around 1 little ones per pregnancy, which happens around 1 times a year. Fully grown, they reach a bodylength of 6.8 cm (0′ 3″).
