I found these cats on my willow tree. It is a young tree. Are they bad ones? What should I do?

I know you are concerned about rust. Wipe the yellow spot. If it comes off it may be rust. I suspect, though, it might just be the tree objecting to the catapillars. Treat that problem and see if the other problem goes away.

The following excerpt from http://www.uky.edu/Ag/Entomology/entfacts/trees/ef423.htm

Quoting:
Prevention and early control is important. Removal and destruction of the egg masses from ornamentals and fruit trees during winter greatly reduces the problem next spring. In the early spring, small tents can be removed and destroyed by hand. Larger tents may be pruned out and destroyed or removed by winding the nest upon the end of a stick. Burning the tents out with a torch is not recommended since this can easily damage the tree.

Young caterpillars can be killed by applying an insecticide containing Bacillus thuringiensis var kurstaki. Other insecticides include carbaryl, methoxychlor, and malathion. Larvae within the tents are protected beneath the webbing and are more difficult to kill with an insecticide.


Hope that helps.
Carol

Thanks! I only noticed about 5 of these and I can easily reach them. Tomorrow I will go back there and pull them off. I'll get DH to squash them becasue dead they will be. Thanks for taking the time to look this info up.

I'm pretty sure it's a Poplar Tentmaker Moth larva, Clostera inclusa.

No doubt you're right. In any case the rememdy would be the same, yes? Handpick or use Bt

Dawn, good job catching it with only 5 catapillars! How observant! What a good willowmom.

A broom works well too. Sometimes if you tear open the 'tent', birds will do the rest pretty quickly, like before you get back from the store with the Bt
