Description and Identification
Caterpillar
The larvae of these moths have a very unique set of patterns involving two large eyespots on both sides of their head. Their head bulges in size as they mature, making them look like a snake.
Besides this, there is a large eyespot on their rear end, and their bodies are covered with yellow bands and diagonal patterning. A black spine grows out of their rear eyespot.
