Its range includes almost the entire eastern seaboard of the United States, the Great Lakes, and south eastern Canada, making it the most common and broadly distributed pitcher plant, as well as the only member of the genus that inhabits cold temperate climates. The species is the floral emblem of the Canadian province of Newfoundland and Labrador. The species was introduced into bogs in parts of Ireland, where it has proliferated. ==Description== Like other species of ''Sarracenia'', ''S. purpurea'' obtains most of its nutrients through prey capture. However, prey acquisition is said to be inefficient, with less than 1% of the visiting prey captured within the pitcher. Even so, anecdotal evidence by growers often shows that pitchers quickly fill up with prey during the warm summer months. Prey fall into the pitcher and drown in the rainwater that collects in the base of each leaf. Prey items such as flies, ants, spiders, and even moths, are then digested by an invertebrate community, made up mostly by the mosquito ''Wyeomyia smithii'' and the midge ''Metriocnemus knabi''. The relationship between ''W. smithii'' and ''S. purpurea'' is an example of commensalism.〔C. Michael Hogan. 2011. (''Commensalism''. Topic Ed. M.Mcginley. Ed-in-chief C.J.Cleveland. Encyclopedia of Earth. National Council for Science and the Environment. Washington DC )〕 Protists, rotifers (including ''Habrotrocha rosa''), and bacteria form the base of inquiline food web that shreds and mineralizes available prey, making nutrients available to the plant. New pitcher leaves do produce digestive enzymes such as hydrolases and proteases, but as the individual leaves get older into their second year, digestion of prey material is aided by the community of bacteria that live within the pitchers.〔Rice, Barry.
