The images below are a fluttering bug or beetle of sorts, that seemed to been pollinating the larkspur. Can anyone identify this critter and if it's of any value to the garden. Thank you.

It looks like a moth in the Sphingidae family, a hawk or sphinx moth:

I think it may be Hemaris thysbe, commonly known as the Hummingbird Clearwing. They are great pollinators.

Beautiful!
And... They eat those nasty Japanese honeysuckle vines in their caterpillar form!
I'm always thrilled to see the clearing hummingbird moth.... Like you, I shoot pictures until it flies off...

I was hunting for monarchs yesterday when this thing flew by me, I jumped back a bit, and my forearm failed into a fresh purple thistle, thank you birdbug.
