    They don't appear very busy controlling the thistles. Posted 8 years ago

      oh but they are.... the adults do eat the thistle, but that's not what does the most damage. They lay their eggs in the bud and grubs do a lot of internal damage to them - the buds don't open and the plants can't reproduce. Posted 8 years ago, modified 8 years ago
