A European species that feeds on alder was discovered recently in Newfoundland. This is undoubtedly an accidental introduction into North America. Because alder has an extensive distribution in North America, the sawfly is likely to spread. This species, new to the North American fauna, is characterized and separated from native species of the same genus. The documentation of the existence of an additional alder-feeding sawfly and its separation from native species can save foresters, agricultural agents, and quarantine workers time, effort, and cost if control measures are needed. Technical Abstract: Monosoma pulverata (Retzius), a European alder-feeding sawfly, is reported new to North America from specimens taken in Newfoundland. It is separated from the only native North American species of Monosoma, M. inferentia (Norton). |
