Imperial Moth

Look at this handsome green caterpillar! Knowing my interests in critters, my neighbor brought it over to me at lunchtime today. I snapped its photo and posted it on Facebook, asking if anyone could identify it. I'm proud to say that within moments a recent environmental-science grad from my own alma mater chimed in: it's the larva of an Imperial Moth (Eacles imperialis) and will develop into a brown-and-tan moth. Based on the Wikipedia description and images, I believe it's a female, as they have more yellow-green coloration and are fatter.

Speaking of critters, I think the stinkbugs are realizing it's time to seek a warm home for the winter. I had five on the screen door the other day.
