What insect eats my Hollyhock leaves every year to the point that they look like lace? I never see the culprits on the plants!

Skeletonized leaves are usually the work of young catapillars, before they grow large enough to eat the entire leaf. Look under the leaves for them. You may see a flattened, slug-like creature feeding there. Some insects are most active at night, so if you can't find them in the daytime, do a Sherlock Holmes investigation with a flashlight at nite! If you find catapillars, sprays with B.t. as the ingredient are a safe, organic control option. These are available under many brand names. Good luck with the investigation!
