Your gorgeous moth is a Pandorus sphinx moth. The moths in the Sphingidae family all have that fighter jet like shape.
These are found in North America basically east of the Rockies. The larvae are also quite spectacular. The caterpillars do eat grape leaves, porcelain vine (Ampelopsis sp) as well as Virginia creeper.
The adult moths have a long proboscis or feeding tube for gathering nectar from flowers. They look a little like small hummingbirds feeding at night.
Here are some photos of this insect
