Caterpillar Buff-tip

 

Today while cleaning a birdbath, I noticed on the corner of the bath, a soaked wet caterpillar, He was very wet and he tried to get away out of the water. So I took him out.

I remembered I had seen this kind of caterpillar years ago, but did not remember which specie it was. I saved him from the water and put him on a dry spot. 

He looked to me rather big so he might be soon cocooning. He is a caterpillar of the Buff-tip, (Wapendrager)(Phalera bucephala).
