Description: Discovery: An overwintering colony of adult Red-haired Bark Beetles (Hylurgus ligniperda Fabricius) was discovered in November 2000 near Rochester, New York. These European beetles were found during an evaluation of white pine root decline in a Christmas tree plantation. Hylurgus ligniperda was intercepted 169 times at ports of entry in the United States between 1985 and 1994. Excluding these interceptions, individual beetles had only been caught in detection traps in 1994 and 1995 about 15 miles west of the current infestation. The positive trap catch in 1994 occurred in a pine stand damaged by a winter storm in 1991. The lag time between the first detections and the discovery of an overwintering colony might well reflect how long it takes a recent introduction to reach a damage-detectable threshold
