yep sunburn, i am having a problem right now with a black sometimes grey beetle absolutely munching my hostas. t reduces them to lace and then stems. they are tough, i squash them and they continue on with their guts hanging out. they are creep[y. i have over 500 hostas, they seem to like the plain green ones best, but the will take ones with white too. i am sick about it, i just had shoulder surgery so i cant just pick them off and squash them. they are hard bodied and insecticide doesn't faze them.
any ideas? I will get a picture later and start a new thread.
