Oligota pusillima  was found in a pile of decaying and moldy corncobs and cornhusks near a composter in a residential area adjacent to a mixed forest. Mites were abundant in the moldy corncobs and cornhusks where the specimens were collected. Adults were collected during April, August, September, and October.
