From CABI Pest map 035 (1953): Present, restricted distribution

From country itself (1992): eastern areas, including Ontario.
From Looney et al. (2016): first detected in Ottawa (Ontario) in 1922. It quickly became a forest pest in the eastern USA and Canada, but populations could be reduced by biological control programs during the 1930s and the inadvertent introduction of a nuclear plyhedrosis virus. The species has not been an active management concern in North America for many decades.
