Wood Borer beetle



My best guess here that these galleries were done by a member of Buprestidae family. They are irregular, twisting and curling, and growing larger as they progress - the largest point was about 8mm, for 1 - 1,5 mm in depth. Some of galleries are still filled with sawdust and faecal matter (at least, that's what I think those tiny black dots inside galleries are...).


Found on discarded branch, on the side of a pathway through mixed forest (oak, beech, spruce and fir), on lower slopes of Jura mountain range, in Geneva lake valley.
