It is hard to guess what a Great evening bat weights. But we have the answer:
An adult Great evening bat (Ia io) on average weights 49 grams (0.11 lbs).
The Great evening bat is from the family Vespertilionidae (genus: Ia). When reaching adult age, they grow up to 54.2 cm (1′ 10″).
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 great evening bat (Ia io) is the largest bat in the vesper bat family (Vespertilionidae) and the only living species in the genus Ia. It is common to Eastern and Southeastern Asia (China, India, Laos, Nepal, Thailand and Vietnam), mainly living in areas with limestone caves at altitudes of 400–1,700 metres (0.25–1.06 mi). Their roost sites have been found both near the cave entrances and up to 1.5 kilometres (0.93 mi) within the cave systems.
