I’ve seen Luna moths (possibly the most beautiful critter in the class ‘insecta’) as big or bigger than this ‘giant’.

One summer in Kentucky, in the middle of farms and woodlands, I saw a bunch of different giant moths: Lunas, Cecropias, Ios, Polyphemous, and a few others. Tons of different butterflies, too. And green preying mantises easily seven or so inches long.

I saw this Sphinx moth at the local WalMart

I'll agree with that. I've only seen a couple in my lifetime here in Michigan

Here's something I just read:

there are approximately 8 species of moth to every single species of butterfly on the planet.
