Grasshoppers are eating the rubharb

It sounds kinda like a code. Like, "the eagle has landed" or "liberty is on the move."
But no, it's real, grasshoppers are ganging up one one of my two rubharb plants and have brought it quite to its' knees. If rubharb had knees. It's funny they should gang up on just one plant, you'd think they would spread out and eat both plants, so as to not kill them and consume their resources unsustainably. But no... Damn locust, they're just like people.

Post script: I meant to write that yesterday. Today it would seem the problem has solved itself, as both rubharb plants, the asparagus, lettuce, and pretty much everything is now under several inches of snow. So we'll see how things look in spring, for now it looks as though winter has arrived, bring on the ski season!
