The Cypress Bark Moth is a moth
of the Tortricidae
family. It is endemic to Japan
.
The wingspan
is 13-16 mm. Adults are on wing from early June to late July.
The larvae feed on Cryptomeria japonica and Chamaecyparis obtusa
. The larvae bore into the bark and feed on the phloem of a standing tree. The cambium is injured, but since the damaged area is only small, the callus soon heals the damaged part and the tree continues to grow normally, but the scar and discolouration remain and increase annually. These scars lead to a degradation in the commercial value of the timber.
