The hair- tailed bats or red bats ( Lasiurus ) are a genus of the smooth-nosed family (Vespertilionidae), whose representatives are native to North and South America.
The generic name Lasiurus is Greek and means "hairy tail".
description
The hairtail bats have a head-to-tail length of 50-90 mm and a forearm length of 37-58 mm. Adults weigh 6–30 g, with the females being slightly larger than the males. The fur of red bats is usually reddish in color. The tips of the hair are mostly white and the coat is noticeably long and dense.
Way of life
The hair-tailed bats, like most bats, are nocturnal and feed on insects. Some species are known to migrate in autumn and spring . The populations of Canada and the northern United States are moving to more southern regions of North America. Depending on the region, the animals hibernate . During the migration, the otherwise solitary red bats often form large groups, whereby the females can also gather in small groups of up to 50 animals in so-called nurseries in summer. In temperate regions, the animals mate in autumn. The females store the sperm in their sexual organs through the winter. The ovulation takes place in April and May, after which the egg is fertilized by the stored sperm. In May to July, the females give birth to 1–5 blind, naked young animals each time. The representatives of the genus of red bats are among the only bats that usually give birth to more than 2 young animals per litter.
