We were lucky to have fairly low temps throughout our 5-day trip - which is good, because my truck doesn't have air-conditioning. Low, in this case, means anything under 95 to 100° F.
We stopped because of the wildflowers, which were spectacular in places, even though we missed the main show. The moth was sipping evening nectar from some Prince's plume: Stanleya pinnata.
And here's the moth! When first seeing these moths, one is often inclined to think they are small hummingbirds. They hover just like hummingbirds, make a humming or buzzing sound while flying, and dart around very quickly.
The wings are brightly colored, though it's difficult to get them to sit still long enough for perfect photos!
As you can see, they hover over the target flower, and suck nectar through a long proboscis, which is essentially a tubular tongue.
Their wings are usually just a blur, and in this photo the proboscis is coiled.
