Specimen(s) collected during a study of coastal rock pools of Lake Superior at Isle Royale. Two shoreline zones were differentiated using a line between upslope “lichen zone” pools and downslope “splash zone” pools. See citation for details. Distribution — Not applicable. Ecology — Most Smittia larvae in damp soil or decaying vegetation, though some species aquatic. Very few non-adult stages known. Remarks — One IRNP specimen, but from an uncertain zone. Genus determination difficult for terrestrial chironomid genera. Species cannot be determined with exuviae. Notable traits include smoothly rounded anal lobes, no thoracic horns, tergites 2-8 densely covered in spinules of similar size (per segment) except for muscle marks, and no armament between segments.
