This polyphemus moth caterpillar is large, up to three inches, it belongs to a group called the giant silkworms.
The adult polyphemus moth is large and fairly attractive, though it's not in the same league as some of the other
giant silkworm moths such as the luna moth, cecropia moth or promethea moth.
An attempt was made to create a silk industry from these American species, but it didn't work out because the Asian silkworm does a better job.
The polyphemus moth looks pretty alien, with its head partly drawn into the first section of its body, and that crazy looking face and claws.
Their behavior can be pretty strange too, they sometimes make a snapping noise with their mandibles and other
polyphemus moth caterpillars in the area will join in.
