Subject: [MAIPC] beetle on Canada thistle

CAUTION: External Email

  Yesterday in SGL 110 on Blue Mountain in very northern Berks County, PA I saw extensive herbivory on Canada thistle by what appeared to be beetles. The leaves were skeletonized. I have photos but they are not that good as I took them with my cell phone. What am I seeing?
