Checking Vapourer Moth larvae damage
The photograph is courtesy of the family of George Dey. George took many forestry photographs in his forestry career and many are now shown on this web site. Check under ‘Groups’ and George Dey Collection.
No information on this photograph but it appears that some of the Lodgepole pine shoots have been attacked by Vapourer moth larvae and the outbreak is being looked at by Forestry Commission entomologist who could be David Barbour?
