Grasshoppers here, too, and they have stripped some plants! I couldn't figure it out for the longest time, as this is the first year I've seen such destruction. Finally tied it to the grasshoppers. I had no idea they could do such great damage so quickly. Mary

There are both caterpillars and beetles that eat leaves of Eupatorium (and probably numerous other pests). Some of them crawl up and eat during the dark of night. You would have to create a barrier to stop them from finding or scaling the main stem. More than likely they are hiding in the mulch or leaf litter around the base of the plants.

Well I must have an unusual specimen because mine is in full sun, with soil that is sandy loam and very well-drained. I don't water it any more than anything else. I have never noticed that it is droopy or wilting. I have also never gotten ONE seedling! I am jealous of all these posters getting seedlings because I would love to have one or two more of these plants. Mayalena I think you even offered me a seedling at last year's swap, which I didn't take and now I regret it! :) I also love the cloud of white flowers which attract zillions of pollinators late in the season. So odd that we have such different experiences with the same plant sometimes!

Someone on a different forum suggested I go out at night to see if whatever is eating my echinacea leaves is a "night-time" eater and sure enough, I saw something. Can someone tell me what this is and how I get rid of it?
