If you live in Florida and don't know about canna leaf rollers, then it's time you learned. Most of the people I work with here at UF/IFAS would probably agree that leaf rollers are the most troublesome canna pests in our state. In fact, all of the damage that I found on my plant seemed to be the result of a single critter. Sure, it took me a few days between when I noticed the problem and when I checked it out. But still -- that's a lot of damage for just one caterpillar.

The lesser canna leaf roller can be a little harder to discover. These caterpillars are much smaller and typically roll themselves up in the edge of a leaf, where they then feed only on the top layer of the leaf.

Needless to say, that leaf roller won't be bothering my plants again.
