My canna's are in my pond, happily growing like mad. Recently, I've noticed some strange holes in my leaves. It looks like someone took a hole punch, accordion folded the leaf, and punched. It really reminds me of the hungry, hungry caterpillar by eric carle. Any ideas what is doing this?

Those holes look pretty round...I remember reading about a bee that takes little circles from rose leaves, but can't quite remember the name of it. I love Eric's books, my teachers read them all to me when I was smaller

When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant. Mary Ann LaPensee

I do have some groundnesting, leaf cutter bees nesting between some rocks and the driveway. I've never seen them attack the center of a leaf though, my experience has been the edges of the leaf, working inward. I'll keep an eye out and see if I see him/her working on them. Thanks for the suggestion!

Well, I'm not sure, but looking at the second picture, it doesn't happen to be anything to do with that sheepish-looking fellow in the red hat?

lol I sure hope not. I always catch him sitting on a mushroom, petting a cute bird. Maybe it's just an act and he is the culprit.

I had a similar empty dotted line on one of my plants. Something nibbled it while it was still rolled up. Personally, if the 'something' only eats that one leaf, I'm fine; I think it looks neat! Not that I want all my plant leaves sporting peek-a-boo holes, but one is garden character. :~)

If it isnt him, or the bullet-holes left from a drive-by shooting by a jealous rival trying to assassinate him, then I wonder if it could be the very appropriately named 'Lesser Canna Leafroller' caterpillar, which, I learn, is common in southeastern United States and feeds only on plants in the genus Canna. 'The caterpillars fasten the edges of leaves before the leaves unroll or the caterpillars can roll up one side of an open leaf. Within this shelter, the caterpillars feed on the upper surface of the leaves, rarely chewing through the lower epidermis except when the caterpillar bores through the rolled leaves.'
