Ninety-seven species of Trichoptera in 38 genera from 13 families are recorded from insular Newfoundland. Fifty-four of these are new records. -- About 2000 adults were collected and identified by the author. In addition about 700 specimens from other collectors were identified by the author. Also included are the caddis fly collections of the Canada Agricultural Research Station, St. John’s, totalling some 150 previously identified specimens. -- All specimens were collected with “blacklight” fluorescent traps. -- Keys are given to families, genera, and species known from Newfoundland. Illustrations are given of morphological differences separating families and genera. The male genitalia are the definitive species characteristic and all are figured except those of Hydroptilidae. Female genitalia are drawn only if no published figures are available. -- The geographical range in North America is given for each Newfoundland species, with particular emphasis on their known northeastern and eastern distributions. -- The Newfoundland trichopteran fauna, although poorer in species, is apparently similar to the caddis fly fauna a northeastern North America.
