The population is declining due to loss of its habitat, old growth in tall eucalypt forest which has largely been clear felled for tree plantations, wheat cultivation and urbanisation.
[3] The new species was distinguished from Falsistrellus tasmaniensis as being generally larger, specifically the comparative size of skull measurements, the proportionally longer dentary, and slightly bigger glans penis.
It is an insectivore associated with old growth forest that provides the species with its preferred foraging opportunities, this habitat has been greatly reduced by changes in land management or clearing for the wheatbelt.
[3][7] The bat hunts flying insects around the leaf canopy of tall forest, in the valley between tops of trees or the open areas above the mid-storey.
[8] The range is dominated by wet sclerophyll eucalypt forest and semi woodland of the southwest, bounded by arid and agricultural regions to the centre and north.
[3][8] They have also been recorded in remaining stands of older tuart forest (Eucalyptus gomphocephala), another tree giant of the south-west now greatly reduced in range.
Competition for suitable tree hollows from feral animals, honey bee colonies and the introduced parrot Trichoglossus haematodus, reduces their availability and so considered a threatening factor to the presence of the species.
[1] The once extensive jarrah forests, mostly clearfelled and later managed by forestry practices, provides rich habitat that suits the morphology of this larger species.
[3] Despite searches for the species in the northern extent of its recorded range, it was not found beyond Mandurah at the Swan Coastal Plain or Collie in the Jarrah Forest regions.
[3] The northernmost record of the species was Jandakot, until the investigation of faunal assemblages during the holocene period unearthed fossil specimens at the East Moore cave area in the north of the Swan Coastal Plain.
