Nearly every day there are at least 4 or 5 Snowberry Clearwing moths (Hemaris diffinis). As its name implies, part of its wing is clear (not covered with scales) as you can see from this photo.
It is a hawk moth and among the few moths that can hover like a hummingbird which is why it is so hard to actually get a photo of its wings because they are in constant motion.
Their coloring is slightly different from the Hummingbird Clearwing (Hemaris thysbe) which I just discovered also out on my butterfly bush (!!!)...
or the Hummingbird Hawk Moth (Macroglossum stellarum).

At least the Snowberry Clearwing has a more unique name once you figure out which species it is. Why snowberry? Because the larvae of this moth feeds on (among other plants) snowberry.

Also have had visits from the Eastern Tiger Swallowtail (yes, Lynne, I labelled ALL my photos Western Tiger Swallowtail!!)
This beautiful little dragonfly is also a frequent visitor. He has a blue tail and green head. (The dragonflies tend to prefer the dead flowers and not the newly opened ones. Would love to know why.)
The steel blue cricket hunter wasp is back too. It flies around the butterfly bush, but actually seems to prefer the hydrangea. The photo is not totally in focus, but you can see where it gets its name as far as color. It doesn't stay still very long either.
You can read more about it here.
I saw a black swallowtail for the first time today, but was unable to get a photo. So you will be forced to look at more butterfly bush photos at a later date!
