Found this snowberry clearwing, aka hummingbird moth (many people mistake them for "baby" hummingbirds), under my deck umbrella one chilly morning a few weeks ago. Didn't want it waking up only to batter itself to bits under the canopy (they typically have that hairless spot on their back), so I took advantage of its near-frozen state to get a few photos that would be nearly impossible under other circumstances.
When disturbed, clearwings flicker their tail, um, feathers. Rather like a miffed cat thwapping its tail, I suppose...
Well, it was cold! That was the best it could do.
