|If you look closely, you can see 4 corn rootworm adults on my first Rose Mallow bloom of the season. Row corn is planted closer to us this year, so those beasts got here sooner than last year.
A couple evenings ago, I went out to shake the beetles into a bucket of water. And found some already had gone into the unopened flowers. I got them out and early the next morning, they were hardly on the Rose Mallow, but a couple of hours later!!! Last year was the first year they bloomed for me and I was so thrilled.
Articles say the rootworm beetles prefer yellow composites, but oh! not these. We've got yellow composites all over the place between the native sunflowers, Black-eyed Susans, Ox Eyes, etc. They are on some of these flowers, but their greater numbers seem to be onthe more tender plants, like this hibiscus and the Tick Trefoils I just got this spring.
I'd like some of the Rose Mallow to go to seed, so I just may need to hand pollinate. I've never done this before, but I am sure there is an article somewhere about it. And I will give your idea a try! I just need to find some of these. Wal Mart has a large craft area, so will check there first. I want to collect some Spiderwort seeds and think this might help catch them.
Thank you for linking to your idea. I could not remember where I saw it earlier... here or somewhere else.

My biggest problem has been Hibiscus Beetles, Althaeus hibisci. The larva enter the seed just when they are starting to grow, then eat the seed from the inside. This year I bag them when the buds where starting to form and so far I have not seen any sign of damaged seeds.
