It is hard to guess what a Silver-haired bat weights. But we have the answer:
An adult Silver-haired bat (Lasionycteris noctivagans) on average weights 11 grams (0.02 lbs).
The Silver-haired bat is from the family Vespertilionidae (genus: Lasionycteris). It is usually born with about 1 grams (0 lbs). They can live for up to 12 years. When reaching adult age, they grow up to 18.7 cm (0′ 8″). On average, Silver-haired 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 silver-haired bat (Lasionycteris noctivagans) is a solitary migratory species of vesper bat in the family Vespertilionidae and the only member of the genus Lasionycteris.
