Myllaena audax
Myllaena audax is a species of rove beetle in the family Staphylinidae, described by Thomas Lincoln Casey in 1911. It belongs to the subfamily Aleocharinae, one of the largest subfamilies of rove beetles. The species has been recorded across northern North America, with documented occurrences in Canada from British Columbia to Newfoundland and Labrador, and in the United States from Alaska to the Northeast and across to the Pacific Northwest. Like other members of its genus, it is likely associated with moist habitats where it functions as a generalist predator or scavenger, though specific ecological details remain poorly documented.
