Excellent site, thanks. Its the caterpillar of a buff tip moth. I now know what the eggs look like, so I can keep an eye open. They pupate by falling on the ground, so I'll see what sort of destruction I can do underneath the trees too so they don't come back next year.

 

Excellent site. I hate killing things just 'cause they're on the plants. Nice to have some positive I.D.'s
