When the moth is ready to emerge from the cocoon, it makes a special juice which softens the cocoon so it can push its way out. The newly hatched moth's wings are wet and wrinkled. The moth will spend an hour squeezing fluid from its body into the wings. Then the Polyphemus moth will remain motionless for the rest of the day to let its wings stiffen and harden. Adult moths do not eat or drink.
Moths are active at night and rest during the day.
The female moth has a fatter body and very skinny antenna. The male moth has a trim body and wide feather-like antenna. The male moth will take to flight looking for a mate. The female moth will generally not fly until she has mated. Then she will then take flight to lay her 200 - 350 eggs.
