Abstract
Lobesiodes euphorbiana (Freyer) (Lepidoptera: Tortricidae), commonly known as the spurge leaf tying moth, was intentionally introduced into Canada in the 1980s as a biocontrol agent for leafy spurge, Euphorbia virgata Waldstein and Kitaibel (Euphorbiaceae). The moth has never been reported in the United States of America, where it was not approved for release as a biocontrol agent. Here, we report the first records of L. euphorbiana in Montana and North Dakota, United States of America.
