Sphinx moth in flight

描述：

The White-lined Sphinx Moth (also sometimes called a "hawk moth," Hyles lineata) is also sometimes referred to as a "hummingbird moth" since they fly very energetically. They consequently require a lot of nectar. Like a hummingbird, they rarely hold still for more than a moment or two.The plant is the locally native Oenothera elata var. hirsutissima grown from local genotypes. Each flower only lasts for one night.August 11, 2014, Salt Lake County, Utah, in horticulture, at about 9:15pm.
