First off I did have to say Eww! It is an amazing picture of a spider but oh it creeps me right out lol. But the real reason I came here is to see if anyone knew if this catapilar is a concern. We found it on our plum tree. It was so neat and unique looking we couldnt kill it. But we did relocate it. Wondering if anyone knows what it is. and if I see another if I should dispose of it.
