The adult females resemble the bud of their coniferous hosts, [4] hence the name bud scale. Physokermes are difficult to identify to species, as only pre-reproductive females can be used. [4] Once females begin to oviposit, their bodies become distorted and it is not possible to detect the morphological features necessary to identify them to ...

The spruce bud moth defoliates young white spruce trees, and after 1980, upon the plantation of extensive regions of white spruce, has been considered a pest. As mentioned, the larvae of the spruce bud moth, in particular, deform the buds of the spruce tree greatly, specifically destroying the cortical tissue and crown of the tree, weakening ...
