Barry photographed this pretty beetle at the FWG. Goldenrod and leatherwings seem to go naturally together. Bug Guide calls them goldenrod soldier beetle, which is far more apt I guess, but the Pennsylvania leatherwing name is used in most insect guides, no doubt because of the species name (pensylvanicus). At the height of their occurrence, which is usually mid-late August (although they can continue to be observed well into September), they can be abundant on goldenrods. They are actually soldier beetles (Cantharidae), and a good insect to have around as their larvae feed on various insects we don't always want in our gardens, such as aphids.
