Glen Cove, Pikes Peak treeline, on Sedum rhodanthum flowers.
This late in the season (September 2) many animals have lived their lives and have left offspring to hibernate through the winter. In terms of insects, little is flying now compared with mid-July. But here are a mating pair of Mountain Blues (Agriades rustica) and a third, an onlooker. They should have gotten a room. Yarrow blossoms are pretty exposed.
And the late-blooming Rudbeckia plays host to quite a few butterflies and even a wasp. I’ll put some determinations on these when I get them. The butterflies are, clockwise from top, the zephyr anglewing (Polygonia zephyrus), Milbert’s tortoiseshell (Nymphalis milberti), and again, the mountain blue (Agriades rustica). Tiger beetles are having a great time of it on the damp sand above Glen Cove.
This, I think, is a Sphecid:
And in the rockslides I found four marmots, looking a lot like rocks, sunning themselves and barking at me.
