Tasmania is home to eight species of insectivorous microbats (family Vespertilionidae), which are vital for pest control by consuming up to 50% of their body weight in insects nightly. These small, echolocating mammals—including the tiny little forest bat—roost in tree hollows, under bark, and sometimes in buildings.
Key Microbat Species in Tasmania:
Little Forest Bat (Vespadelus vulturnus) - Smallest,
Southern Forest Bat (Vespadelus regulus)
Large Forest Bat (Vespadelus darlingtoni)
Chocolate Wattled Bat (Chalinolobus morio)
Gould’s Wattled Bat (Chalinolobus gouldii)
Lesser Long-eared Bat (Nyctophilus geoffroyi)
Tasmanian Long-eared Bat (Nyctophilus sherrini) - Endemic to Tasmania.
Eastern False Pipistrelle (Falsistrellus tasmaniensis)
Important Facts & Conservation:
Appearance: Often mistaken for mice with wings, they are 40 to 75mm long.
Activity: Active at dusk, often seen flying quickly around trees and streetlights.
Habitat & Threats: They rely on old-growth tree hollows for roosting, making them vulnerable to habitat loss.
Safety Notice: Do not handle microbats as they can carry Australian Bat Lyssavirus. If you find one that is injured or on the ground, contact Bonorong Wildlife Sanctuary or a local vet.
Injuries: They are often injured by cats, flypaper, and house renovations.
Where to See Them:
They are found across Tasmania, particularly in forested areas like Douglas-Apsley National Park, Mount Field National Park, and Mount William National Park.
They can also appear in suburban areas, including Seven Mile Beach, Lauderdale (known fact) and can sometimes decide that YOUR HOUSE, walls/roof are the most desirable real estate!
Although some may consider that they have a face only a mother could love, they are absolutely adorable and play a key role with flying pest control, I would like an army of them!
When they take up residence within your home, I can safely encourage these little legends to vacate at certain times of the year (late March - mid-April) without any harm at all having recently successfully conducting a 4 week exclusion program in Seven Mile Beach :)
