growing outdoors and caterpillars

[mook1178]

I moved many of my Phals outdoors for the summer. I live in northern Delaware and the temps and humidity in the summer have made them grow plenty of new roots. I have had a problem with caterpillars eating the leaves and some root tips. I have them sitting on the ground under a few bushes to keep them shaded.

What can I do to lessen the chance of getting eaten next year? I think most caterpillars in my area have morphed already as I do not see much evidence anymore.
