Adults of Scolioneura betuleti (Klug.) were first collected in Canada in 1983 near Newmarket, Ontario. The adults were first identified in 1984 and the species was f1I'St reported as S. betuleti by Evans et ale (1985). We believe this to be the first North American record of the species, which is the spring unit of a complex of two species in Europe, S. betuleti and S. betulae Zadd. (Goulet, personal communications, 1986, 1987). The taxonomic relationship of these insects is incompletely defined as we are awaiting the results of studies of the holotypes in Europe, but the species in Ontario has been tentatively identified as S. betuleti (Klug.) (Goulet, Biological Research Centre [BRC] lot # 83-1054, Forest Insect and Disease Survey [FIDS] # 835-0097). A study of this leaf edgeminer was begun in 1985 and continued throughout the summer of 1986 near the city of Newmarket in central Ontario.
