Endria inimica is a wide-ranging species found from British Columbia to Quebec and at least as far south as Oklahoma.
The species is sometimes reported as a pest of grasses.
Endria inimica can be separated from similar species by the three pairs of dark spots, one pair on the head, one on the pronotum, and one on the basal part of the scutellum.
