Southwestern Naturalist 38 (3) 252-274. PDF Quote from page 254: "Dodds (1923) simply stated that a few specimens of A. subnotatus were found in South Boulder Valley. There is some question as to whether those specimens or the concept of Traver (1935) are applicable to this species. The species has not been reported in ecological studies and has not been clearly defined. According to J. Zloty (pers. comm.), who is presently revising the genus Ameletus in western North America, A. subnotatus is a northern boreal, transcontinental species. See also Remarks under A. aequiuocus, above."

PDF - caution 46MB Elevation collected 7,600-4,950 ft. Adults were found in April. Quote from page 16: "Remarks: Larval exuviae of this Ameletus species often are found in abundance clinging to exposed surfaces along the edges of the middle and low reaches of the Cache la Poudre River in early spring. Dodds (1923) reports "a few specimens have been found in South Boulder Valley [Colorado], exact locality unknown. Zloty (1996) did not include these Boulder County records in his revision of Nearctic Ameletus so the status of A. subnotatus in Boulder County is not verified. This species is probably more widespread in the SPRB than records indicate." |
