Snowberry Clearwing Moth
I was hoping to catch a shot of this moth and today found one depositing eggs and several nectaring. I also found the very similar Hummingbird Clearwing Moth and had both of them in the same patch of thistles.
These moths can be told from the similar Hummingbird Clearwing by the Snowberry's black legs and black band running through the eye and down the side of the thorax.
