Question From: S. Saltmarsh - Cordova, Alaska, United States
Q: I live in South Central Alaska. My larch tree that was grown from a seedling, is now about 20 foot tall. For the first time this year I noticed closed green cones! Yesterday we noticed inch long "caterpillars". Black headed, pale greenish, with paler undersides; they are eating the needles, so have defoliated branch sections. The tree is still very healthy looking. From your information just read, I can't tell if they're a Casebearer or a Sawfly. What can I do to save my beautiful tree?. Thank you for any help.
