Blackburn's Sphinx Moth? (Oahu)

Need help identifying, I'm certain its a Blackburn's Sphinx Moth. But didn't see Oahu listed as having a known population on the DLNR website and wanted some more information on it before I go making a big deal about it. As I found it in a military facility. I can't just report it to DLNR, it has to be reported up the chain and I'm fairly sure most of the army higher-ups don't care about a moth endangered or not. Mainly just need to know what it is exactly and if it has a known population on oahu, before i go up the chain making a huge fuss about it.

Edit: Also, after several google seaches this native species hasn't been seen on oahu since the 70s, not too sure how true that is or how up to date that statement is but never the less I'd still like a second opinion before reporting up the chain.
