Cryptarcha ampla has been recorded in Canada from British Columbia east to Québec and Nova Scotia ( McNamara 1991; Majka and Cline 2006), and in the United States from Maine south to Florida and Alabama, west to Texas, Missouri, Kansas, Iowa, Wisconsin, Colorado, and California ( Parsons 1943; Chandler 2001; Price and Young 2006). The species is found at sap flows on maple, oak, hickory, and willow ( Parsons 1943; A. Cline, pers. obs.) as well as in fungi and at lights ( Downie and Arnett 1996) and is associated with oak wilt fungus mats ( Cease and Juzwik 2001). Price and Young (2006) reared a specimen from the stem of a milkweed ( Asclepias syriaca L., Asclepiadaceae ).
