How to Care for Luna Moth Cocoons

With velvety green wings that seem to shimmer, the luna moth is considered to be one of the most unique moth species in the United States. With a wingspan of up to 4.5 inches, they are also one of the largest. When in caterpillar form and ready for metamorphosis, it builds a cocoon using leaves and silk that it spins from an area near the mouth. Approximately three weeks later it emerges as a moth, typically in mid-morning. By nightfall, the wings have inflated and the new moth takes flight for the first time.

Things You'll Need

Container - 11 inches by 11 inches
Paper towel
Knife
Stick
Plant mister

Instructions

- 1
  Place the cocoon on a small piece of paper towel in an enclosed container that is a minimum of 11 inches high and 11 inches in width or diameter. The enclosure must have good air circulation but should not be open on any side to prevent escape. If the container has tight fitting lid, use a knife to cut small air holes across the top of the enclosure.
- 2
  Place a branch or stick in the housing enclosure to give the moth a place to hang and dry its wings once it has emerged from the cocoon.
- 3
  Use a plant sprayer to spray the cocoon habitat very lightly with unchlorinated water every other day. Do not aim the spray directly on the cocoon, or allow the cocoon to get too wet.
- 4
  Release the moth into a shady spot a day after it emerges from the cocoon, which should be approximately two to four weeks after placing the cocoon in the container.
