Vol. 90, No. 4, October 1979 167 A CHECKLIST OF CADDISFLIES (TRICHOPTERA) FROM MASSACHUSETTS' Richard J. Neves 2 ABSTRACT: Collections of adult Trichoptera were made in the Connecticut and Hoosic River Basins, western Massachussets, between 1974 and 1978. Of the 157 species collected, 88 represent new records for the state. A complete checklist of previously published and newly recorded species is presented, totaling 189 species. Initial records of caddisflies from Massachusetts were first assembled by Banks (1892), who later added several species to the state list. These early collections were made primarily in the eastern part of the state, while Betten (1934) and Flint (1960) provided additional collection records for western Massachusetts. Other reported species are scattered throughout the literature, and much of the early species nomenclature has undergone change and synonymy. A current and more complete list of species is therefore needed. From 1974 to 1978, I collected Trichoptera by light-trapping and sweep-netting along aquatic habitats in the Connecticut and Hoosic River Basins, Franklin, Hampshire, and northern Berkshire County, Massachu-setts (Fig. 1). The 31 sampling sites in the study area represented diverse habitats to more completely sample the caddisfly fauna (Table 1). Most collecting sites in Franklin and Hampshire County were light-trapped at least twice, early and late summer. From 84 light-trap and 40 sweep-net collections during the 5-yr. period, approximately 40,000 adults were captured and identified. Species identifications were based on adult male specimens; all Trichoptera were preserved in 70% isopropanol and are in the author's collection. Light-trap collections of Hydroptilidae have not yet been examined. Checklist of Species The list below contains 157 species collected during this survey with month(s) and site(s) of capture. Additional species will undoubtedly be reported as more extensive sampling occurs in other counties of the state. New records are indicated by an asterisk (*); 32 species not collected during this survey but previously reported from Massachusetts are included with 'Received April 27, 1979. 2 Virginia Cooperative Fishery Research Unit, Department of Fisheries and Wildlife Sciences, Virginia Polytechnic Institute and State University.
