Hi Alex,
This gorgeous Long Horned Borer Beetle is a Blue Rosalia, Rosalia alpina, and we have read that it is becoming quite rare in Europe.  According to Wikipedia:  “They are distributed from the Alps east to Slovakia. Its numbers across Europe has greatly depleted in recent years, and it is a protected species in Germany, Hungary, Poland and Slovenia.
”  The Blue Rosalia has appeared on numerous European stamps.
