The soybean aphid, Aphis glycines Matsumara, was first found in the United States in Wisconsin in the summer of 2000. Since that time it has spread to 21 states, primarily in the upper Midwest and 3 Canadian provinces. The predicted range of soybean aphid includes all of New England, but it had not yet been reported from Connecticut and Massachusetts. I surveyed two sites in each state during the summer of 2004: Hamden, CT on 4 August, Cromwell, CT on 1 September, and Plainfield, MA and Conway, MA on 10 September. Soybean aphids were present at all four sites. This is the first report of soybean aphid for Connecticut and Massachusetts.
