Cryphalus piceae
Fir bark beetle Cryphalus piceae
Pest develops under the thinner bark of older fir trees (in the upper part of the crown) and on trunks of younger trees. The first swarming goes on in early spring (March-April) and the second one in July and in August. The female excavate a small flat maternal gallery under the bark, from which run out quite irregurarly star-like larval galleries. It occurs commonly everywhere with fir trees. It is easy to overlook. It prefers severely weakened or dying trees.
