Excerpt: During late June and early July, 1965, it was apparent that plantations of Scotch and Austrian pines in various Michigan counties were being damaged by lepidopterous larvae mining in the pith of newly developed lateral and terminal branches. Infested samples were examined by Dr. William Wallner, Department of Entomology, Michigan State University, and an attempt was made to rear the extracted larvae. Although as many as two larvae were present in some of the shoots, none survived and no adult moths were secured. A series of larvae was preserved for future study.
