The Arvicolinae are a subfamily of rodents that includes the voles, lemmings, and muskrats. They are most closely related to the other subfamilies in the Cricetidae. Some authorities place the subfamily Arvicolinae in the family Muridae along with all other members of the superfamily Muroidea. Some refer to the subfamily as the Microtinae or rank the taxon as a full family, the Arvicolidae.
The northern bog lemming is a small North American lemming. It is one of two species in the genus Synaptomys, the other being the southern bog lemming (Synaptomys cooperi). Very little information is available about this species' life as they are hard to find and study. The northern bog lemming is a small, reddish-brown rodent with a short tail, and distinct markings on their upper teeth. These markings, along with having four pairs of teats, distinguishes this species from the southern bog lemming. The northern bog lemming lives in wet habitats in North America and is omnivorous, eating herbaceous material and invertebrates. They are thought to be extremely sociable animals and sexually mature at around 6 weeks old. Predators include most medium to larger sized carnivorous and omnivorous mammals that eat smaller mammals. The northern bog lemming is listed as a species of "Least Concern" by the IUCN Red List and is considered threatened or of concern in states such as Minnesota and Maine.
The southern bog lemming is a small North American lemming. Its range overlaps with the other species in genus Synaptomys, the northern bog lemming, in southeastern Canada, but extends farther south.
Lemmini is a tribe of lemmings in the subfamily Arvicolinae. Species in this tribe are:
A lemming is a small rodent, usually found in or near the Arctic in tundra biomes. Lemmings form the subfamily Arvicolinae together with voles and muskrats, which form part of the superfamily Muroidea, which also includes rats, mice, hamsters and gerbils. In popular culture, a longstanding myth holds that they exhibit herd mentality and jump off cliffs, committing mass suicide.
Euschoengastia peromysci is a mite in the genus Euschoengastia of the family Trombiculidae. Recorded hosts include the cotton mouse and marsh rice rat in Georgia; the northern short-tailed shrew, northern red-backed vole, northern flying squirrel, rock vole, white-footed mouse, and deermouse in Tennessee; and northern red-backed vole, southern bog lemming, masked shrew, and eastern red squirrel in North Carolina, among others.
Listrophorus is a genus of parasitic mites in the family Listrophoridae. North American species with their hosts include:
Prolistrophorus grassii is a parasitic mite in the genus Prolistrophorus. It was described as Listrophorus grassii in 1954 from the marsh rice rat in Georgia. In 1974, Fain and Hyland placed it in Prolistrophorus and in 1984, Fain and Lukoschus redescribed the species on the basis of collections from the marsh rice rat in Georgia, Alabama, and Florida and the southern bog lemming in Indiana, West Virginia, and Iowa.
Synaptomys australis, the Florida bog lemming, is an extinct species of bog lemming that occurred in Florida during the Late Pleistocene.
