Buprestidae
My best guess here that these are exit holes from galleries made by a Flatheaded borers, or larvae of some members of Buprestidae family. The adults are known as Jewel beetles or Wood-boring beetles, while the larvae are named as mentioned.
Found on a discarded felled log and bark fallen off it on a forest floor of mixed (oak, beech, fir and spruce) lowland forest, hills in Geneva lake valley, at the feet of Jura mountain range.

Love that last shot. So many different sized creatures crossing paths.
