Tansy Beetle

I've been reading up on Tansy Ragwort and how to get rid of it. It seems the Cinnabar moth and the Tansy beetle have controlled the plant in areas of the Western states. Well, not in my neck of the woods. Tansy ragwort is abundant.

Upon inspection of the tansy plants, I did discover several of these cute little beetles - another import from Europe. They feed exclusively on tansy, and lay their eggs on the plants. WAHOO! A few thousand more of them would be good. I'm not seeing as many Cinnabar caterpillars as I would like to, but the natural forces are at least in the area.
