 Hi, I'm not a coleopterist and presently I have no books about Coleoptera with me, but I remember that when I was 14 years old I collected a beetle like this one : Rosalia alpina (if I had a good memory). This species is to be found on Salix trees (?).

Rosalia alpina, mostly on beech - Fagus, in other trees rarely. In Romania in Karpathians very common in some places. This is not rare beetle in this region.

Yes,it's a male Rosalia alpina,found in old Fagus forests,above 1000 meters altitude(here I must say that one time -and only- I found a male on Platanus orientalis and at really low altitude of about 300-400 meters).It's a saproxylic species and the larvae feed in the sap wood of old,hollowed Fagus trees. It is considered as threatened and is protected,but I know a great habitat near my home here,where it is really VERY common in july on the cut Fagus wood or on the hollowed Fagus. The date that you found this male is very early.

Thanos, you are far to the south. Here is no problem find them at 250-300 if biotop is correct (old Fagus trees). it is rare in western Europe but in Karpathians it is not for sure.
It is protecte but see several hundreds daily is no problem during sommer on "good" places.
