We have tons of moths here in New Brunswick. Most are the average 2-4 inches head tip to wing tip. Every now and then, some Luna Moths show themselves, and away from the city, there are literally monsters.

This guy showed up at work last week. I've never seen one this big inside city limits before. Easily 4 inches body alone. Wondering if anyone here has seen or can identify this guy for me. Thanks in advance

First shot was with the 50-200mm for a 'full body' shot. 2nd one with the Tak 55mm + 12mm extension.

I love that moth! It's like some puffy Bear Pegasus or something.
