dune thistle, Cirsium pitcheri

Often called Pitcher's thistle, this plant only occurs on the shores of Lakes Huron, Michigan, and two spots on Superior. The fellow travelers one encounters while finding these images are always fun. And, as with this strange larva, a little mysterious. No idea what this is! Dune thistle's life story is a little like century plants. It can live up to eight years, flowering and dying in its last season. Most thistles live only two years. Dune thistle occurs on sandy shores in IL, IN, MI, WI, and ON. It is listed as threatened in all these locations, as well as being federally threatened. Mackinac Co MI, 7/12/11.
