Hello fellow Permies,
I found these caterpillars chowing down on my Jerusalem Artichokes this morning. Its early fall, September, and they managed to eat about an 1/8th of one plant so far.
I think I have correctly identified them as Gorgone Checkerspot caterpillars. I took some of the caterpillars off the plant and placed them in a jar near a wasp nest. I haven't seen the wasps eating them yet.
If anyone knows a natural predator please let me know.
Thanks
