LESSER MOUSE-EARED BAT
Myotis blythii
DESCRIPTION
The Lesser Mouse-Eared Bat (Myotis blythii) is a medium-sized bat characterized by its large ears and a distinctive mouse-like appearance. Its fur is typically brown or gray, with a lighter underside, and it has a wingspan of about 25-30 cm. This species is known for its echolocation abilities, which it uses to navigate and hunt for insects in the dark.
FUN FACTS
- The Lesser Mouse-Eared Bat is known for its impressive echolocation skills, which allow it to hunt effectively in complete darkness
- These bats can consume up to half their body weight in insects each night, making them important for controlling insect populations in their ecosystems
- | Unlike many other bat species, the Lesser Mouse-Eared Bat has a unique roosting behavior, often choosing to roost in human-made structures, which can lead to interesting interactions with people
- They are also known to migrate seasonally in search of warmer climates during the winter months

IUCN Red List Status
- Population Status
- The population is currently stable, but local declines have been noted in some areas due to habitat loss.
- Wild Population Estimate
- unknown
- Population Trend
- Stable
- Endangered
- 0
- Threats
- Main threats include habitat destruction, particularly the loss of roosting sites, and pesticide use that reduces insect populations. Climate change may also impact their habitats and food sources.
- Predators
- birds of prey, such as owls and hawks; larger mammals like cats may also pose a threat.
- Defense Mechanisms
- They rely on their ability to fly quickly and use echolocation to evade predators.
- Found in Zoos
