Death in the garden

Finally got back to body pump this morning. It is going to hurt tomorrow.

Wandered around the garden in search of a blip and saw this caterpillar on the tree peony bud. It seemed to be dead - no idea if it has died in situ or been dropped by a bird. No idea what kind of caterpillar (think it is a caterpillar rather than a beetle larvae) it is.

Wonder if it had succumbed to the cold in the recent change in temperature?

Any clues to the cause of the death in the garden or the victim's identity?
