Among the most mysterious and beautiful of all moths are the Catocalas or Under-wings. These moths rarely come to light, but can be trapped by putting out a sweet bait of mashed bananas, stale beer and molasses on logs and trunks of trees in a forest or woods. This bait should be put out just before dusk. Then, when you come with a flashlight to the bait, you will often be rewarded by seeing underwings sipping daintily around the border of the bait. Some even become half-drunk with the delicious mixture and stagger about when they try to fly!
