Mediterranean flatheaded rootborer
This Mediterranean rootborer catched my eye when flying by because of it's sheer size of about 5cm.
It seems to be a pest. I found this on internet:
Damage of Capnodis tenebrionis
Both adult beetles and larvae damage plants. Adults feed on twigs and young branches mainly causing problems in tree nurseries and young plants. The greatest damage is caused by the larvae. Immediately after hatching they penetrate into the roots of the trees and feed on the cortex. They form long sinuous galleries full of sawdust. Young trees die as a result of this damage. A few larvae can also cause thedeath of an adult tree in 1 or 2 years.

The Mediterranean flatheaded rootborer is a large Metallic Woodborer in the Capnodis genus. It is generally considered a patch due to their larvae nesting in an consuming the cortex of mostly young trees.
