Collection and habitat data.

Campbell (1973, 1988) reported that most specimens of this northern transcontinental species were collected from under animal dung or decaying mushrooms. Adults were also collected from the mouth of animal burrows, in leaf litter and other kinds of decaying organic matter. In Alberta, Tachinus frigidus was considered to be a mature forest (conifer-dominated) specialist ( Pohl et al. (2007). The only specimen from New Brunswick was collected from a decaying fleshy mushroom during September in a mature, coastal red spruce forest.
