Answer
Paul,

There are a number of insects that will do this kind of damage, called "skeletonizing". You might try something like spinosad which is a very low toxicity insecticide derived from soil microbes. See http://www.livingwithbugs.com/spinosad.html for info about spinosad. Most healthy plants will recover from this kind of damage once the feeding is stopped.
