Branch-like Caterpillar in Cottonwood is an Ilia Underwing Moth Caterpillar

“Can you help me identify what type of caterpillar this is?” asks Suzanne in her submission regarding the caterpillar pictured below. “I live in Fredericksburg, Virginia. And it was resting in a cottonwood tree. It measured about five inches long. Thank you!” Firstly, we have to compliment Suzanne on the gorgeous photo. The lighting, colors and detail are just incredible, and are very helpful to us in identifying this creature. Suzanne is absolutely right in identifying this as a caterpillar. Specifically, it is an ilia underwing moth caterpillar. Underwing moths are a genus of moth that is characterized by their colorful under wings which contrast the otherwise neutral or bland colors on their top wings.
