Summertime Nature in Colorado. Arapaho National Wildlife Preserve.
While visiting Arapaho National Wildlife Preserve in central Colorado, I heard what I thought was a hummingbird. But when I finally saw it discovered that it was a very large White-lined Sphinx Moth (Hyles lineata). It was feeding on the Purple Nettle Flowers. It never landed, and kept flying while feeding, and thus the hummingbird sound of rapidly flapping wings. I’ve been told that the large catepillars that the Sphinx Moth come from are voratious eaters that farmers hate.
