I’m sending you to pics of this giant that was in our campsite in Terrace BC two years ago. You can see how big it is in comparison to the loonie. The other pic shows more detail.
I initially though it was a bald faced hornet, but searching through the Internet, the white markings are fewer on the abdominal segments than on this specimen. It could still be a hornet, but a different species than the bald faced hornet. Does anyone know what it is?
