At first glance this weevil appears to be jumping away from the thistle, but it is actually standing on the pale tips of the flower’s spines.
There are over 60,000 species of weevil in the world. While I was not able to identify the one in the photo because it was in the shade, it is possible that it is Rhinocyllus conicus, a species introduced to North America from Europe in an effort to combat invasive milk thistle. The thistle in the photo is not milk thistle, and the observation of R. conicus attacking other thistles over the years means that their intentional release is now prohibited.
