On the ground

Finally I could visit the ONE TREE with Omo again. I'm glad that his orthosis works so well, that he could accompany me. When I tired to blip him in front of the tree, I spotted this tiny bug on it's way though the dry grass.
I've no idea what it is and I couldn't identify it. Any suggestion?
Edit: Thank you MaryElizaR for the identification. It's a Galeruca tanaceti

Thank you MaryElizaR for hosting Tiny Tuesday and the theme "on the ground or down below"
