I had come across a very plump caterpillar when letting my dogs outside. It was on a beach tree, and looked to be in the process of forming a chrysalis, as it was hanging upside-down. It was/ is approximately between 1- 2 long, and is green. It’s face is also green, and has: a continuous white stripe on each side of its body; yellow dashes on it’s back; and three prominent yellow dashed lines going down it’s back. It does have a tail, and has an end that looks similar to a tail-less Silkworm and/ or Hornworm. Overall, this Caterpillar seems to have a build similar to a Silkworm and Hornworm.
I live in Michigan’s Upper Peninsula, which mostly consists of rain forests, and is surrounded by Lake Superior, Lake Michigan, and Lake Huron. Because of these factors, we get a lot of bugs

This is neither a Silkworm nor a Hornworm. This is a Humped Green Fruitworm, the larva of the Copper Underwing, Amphipyra pyramidoides.
