This guy is probably a nasty one:

I think it is a Cerambycinae, Trachyderini. You have to check some other links/literature from your area (maybe agricultureing?) to verify the species. In the links there are some others. Besides, yours might be a juvenile (?) less colored as the adult one. Since bugs are for me just a hobby, I am not as familiar with them as I am with butterflies. Good luck!

Thank you very much, Lars. It is not so hard, you see, there are so many beautiful insects around here...

looks like you got thousands of ammo, asergio - awesome collection
