Extract

In June, 1954, hawthorn trees and shrubs in St. John's, Newfoundland, were severely attacked by small leaf-eating caterpillars. Larvae were talzen from a hawthorn tree, Cratageus sp., at Bowring Park, St. John's West, during the first week of July, 1954, and reared in the laboratory. Moths that emerged were identified as of Swammerdamia lutarea (Haw.) by Dr. T. N. Freeman, Entomology Research Institute, Canada Department of Agriculture, Ottawa, who also noted (in litt.) that this was apparently the first record of the species in North America. Dr. L. G. Davis (in litt.), Economic Insect Survey Section, United States Department of Agriculture, Washington, D.C., later confirmed this observation. Swammerdamia lutarea is now common throughout St. John's and has also been found at Brigus, approximately 50 miles to the west.
