In August, 1963, silver poplar trees in St. John's West, Newfoundland, were severely attacked by small leaf-rolling caterpillars. Larvae were taken from a poplar tree during mid-August, 1963, and reared in the laboraeory. Moths that emerged were identified as of Anacampsis populella Clerck by Dr. T. N. Freeman, Entomology Research Institute, Canada Department of Agriculture, Ottawa, who also noted (in litt.) that this was apparently tlie first record of the species in Canada. Dr. K. Sattler (in litt.), Munich, Germany, confirmed the identification in 1964. Dr. Kelvin Dorward (in litt.), Chief Staff Officer, Survey and Detection Operations, United States Department of Agriculture, Washington, D.C., stated that the only record of A. populella for North America was for Washington State by Clarke (1942). Clarke stated that E. I. Smith of Entomology and Plant Quarantine, Seattle, Washington, reared moths from larvae collected on a species of Salix, and this appeared to be the first record of the occurrence of this species in North America.
