The place where I work is a moth magnet. Every late summer and fall, there are various moths that rest on the front porch or near it.
This morning, this very large moth, OMG, 6 inches across, was sitting on the ground, vibrating. Not sure what that's about!
Anyway just look. Oooooooh!
This guy with the big eye-spots (that's what they call them; I didn't make it up.) (I'll let you know when I make stuff up!) is called a Polyphemous moth, a kind of silk moth.
The lime green Luna moth is in the same family; they are both Saturniidae.
This is the caterpillar, an image from the Internet. The cats are big eaters! Seriously, they have to turn into that BIG MOTH!
They eat birch, willow, oak, maple, hickory, beech, honey locust, walnut, elm and other tree leaves, so they are going to be found near heavily wooded areas. We have lots of woods near here. The caterpillars are inconspicuous at first, but at the fourth and fifth molts, then they get this bright green color. After coccooning up and becoming a moth, its eating days are mainly over.
Adults of this family of moths have only partial mouths, and they do not eat and only live as adults for less than one week. Sex is the name of the game, baybee. Find mates, have sex, lay eggs!
This particular moth was resting but also vibrating. As it turns out, these silk moths are so large that they must warm their flight muscles for
a minute or two before they can fly. They do this by shivering, and after a few moments, they fly off.
I know you can't see this Lined Sphinx Moth very well, but he's striking at rest. In flight he's even more so! Fat-bodied, rosy hindwings, and hovers like a dragonfly at his flowers of choice. He floats around similar to a hummingbird, just quieter.
I told you it was mothy up here!
