I know, I know... I've heard how bad poplar trees are and how they are prone to infection... but I want to save mine if I can.

There are these little black catepillars all over it. They are about the size of a rolly-polly bug. Very little. They eat the leaves, leaving holes in the dying leaves.

Some branches even have a little pile of tiny ones the size of pencil leads; larvae maybe?

I've been going out daily and cutting leaves off whenever I can find a catepillar. That seems to be helping.

The first day I went out, I cut off tons, then just a few each day thereafter.

The tree is only a year old, but it's already 18 feet high, so I can't reach the tops...obviously... but from what I can see, they are concentrated on the bottom branches.

I think I'll try to cut a leave off and get it into a plastic baggie and take it to the local nursery...

But until I have a chance to do that....

Anyone have any ideas what they could be? I've tried all number of internet searches...

Nevermind... I just found it. It's not a catepillar at all... guess I'm not good at this game. It's a cottonwood leaf beetle. http://www.entomology.umn.edu/cues/W...LeafBeetle.pdf
