Description

A report by Forest Examiner A.J. Jaenicke of the Bureau of Entomology regarding defoliation of western hemlock and Sitka spruce between Petersburg and Juneau during the summer of 1918. The defoliation was attributed to a sawfly, most likely Neodiprion tsugae, the hemlock sawfly, and a small lepidopteran, probably Acleris gloverana, the western black-headed budworm.
