Habitat
The Long-tailed dunnart primarily inhabits arid and semi-arid regions of central and western Australia, including sandy deserts, spinifex grasslands, and rocky outcrops. It prefers areas with dense ground cover for shelter and hunting, avoiding more open or heavily vegetated zones. These habitats provide the necessary microclimates for its nocturnal lifestyle.
Diet
The Long-tailed dunnart feeds mainly on insects such as beetles, spiders, and crickets, along with other small invertebrates like centipedes. It hunts actively at night by pouncing on prey in the leaf litter or under rocks, using its sharp senses to detect movement. Feeding peaks during the cooler parts of the night to conserve energy in hot environments.
Behavior
Long-tailed dunnarts are solitary and strictly nocturnal, emerging from burrows or rock crevices at night to forage. They exhibit territorial behavior, marking areas with scent glands, and are agile climbers and jumpers to evade threats. During mating season, males may travel more widely, but otherwise, they avoid social interactions.
Conservation Status
The IUCN status is Least Concern, with a stable population trend across its range. Major threats include habitat degradation from land clearing and predation by introduced species like cats and foxes.
