Kenk R 1972 (citation)- p 21, "Widely distributed, generally in warm ponds, lakes, and rivers in the United States and southern Canada, from the Atlantic to the Pacific coasts."
Kenk R 1944 (citation)- p 15, 'Dugesia tigrina is the most common planarian in Michigan. It lives in ponds, rivers, and creeks, particularly those that drain larger bodies of stagnant water. It is absent in cold springs and spring-fed ponds. One finds it commonly along the shores of lakes on the undersides of stones, or among water plants, but also in deeper water away from shore. The species reproduces either agamically, by fission, or sexually, by egg capsules. Fission occurs in nature mainly during the warmer season, sexual reproduction commonly in late spring and early summer.' p 16, referring to animals collected in South Fishtail Bay, Douglas Lake, Cheboygan County, Michigan. 'The small size of the animals is remarkable (smallest mature specimen, 6 mm; largest, 11 mm.). An earlier note by me (Kenk 1941: 56, footnote) refers to this collection.'
