I am finding these on several of my trees they are usually stuck on the top of the leaf and mostly on new growth. I put them in a ziplock gonna try and see what hatches

Does it look like what I have posted in this topic called "Another (but different) What is this?" I can't get a good look at the egg sacks.

Maybe this will help clear it up

I found mine on the top of my new growth also. I believe mine was orange dog eggs -- Papilio cresphontes. Check out this link, maybe it will help if it is the same thing. Either was you do not want them on your tree.
