Common cardinal beetle, Pyrochroa serraticornis

Every year a few of these beetles appear in the Metre at the end of May and beginning of June, having spent their early stages in dead wood somewhere nearby.

Usually they are very active in the daytime scrambling over the vegetation like slow acrobats. They are quite large beetles and they weigh plants down, so they sway in gentle parabolas from one stalk or leaf to another. There is a scarcer relative, the black-headed cardinal beetle. It does occur in the neighbourhood, but I await the pleasure of welcoming one to M3.
