Blink and it's gone.

While looking for hummingbirds I instead came across this clearwing hummingbird moth (Hemaris thysbe). This variety has a green, furry back and burgundy bands on its tail section. They move so quickly they are a challenge to photograph; I only managed a photo of this guy because it stopped for a split second to feed at this plant's tubular flowers, and then disappeared.
