Leaf rollers. They only infest my cannas, but I have lots of cannas. They sew the leaves shut. You can actually see the threads on the rolled up leaves. They lay their eggs inside. They hatch into ugly caterpillars and eat the epidermis of the foliage. So you end up with rotten-looking shredded leaves. It's almost impossible to keep up with them. I unroll the leaves and feed the cats to my fish, but "Mama" comes back and starts in again with her "fly-by-night" attacks. After a while, I just give up. So right now, most of my cannas look like crap. Surprisingly, a couple of cultivars seem to resist the leaf rollers. Wish they all did! Even thunbergis bacillis isn't quite effect on this little buggers.

Below is Tama Tulipa who seems to deter the leaf rollers somehow. Not a scratch on her.
