On window under light. Smaller than the Greater Grapevine Looper. Common name should be Lesser Grapevine Looper. Edit: Can't tell Greater and Lesser Grapevine Looper apart according to Bugguide.
Measured FW is only 14mm. Compare with this previous example which I'm now going to ID as Greater Grapevine Looper: http://www.inaturalist.org/observations/956706
