Tritomegas bicolor

It is found across North Africa, Europe and Central Asia,[1] although in the British Isles, it becomes rarer towards the north, and is absent from Scotland and Ireland.[2] T. bicolor lives mainly on the ground, but is also visible on its host plants — chiefly Lamium (dead nettles) and Ballota nigra (black horehound).[2]
