Polyphmeus Moth update ~ The evening of the day that Jane’s female Polyphemus Moth emerged, she found two males outside the net enclosure eager to get in and meet the female. Amazingly, the wild males had found the captive female by the pheromones that she began to release soon after emerging from her cocoon. The purpose of the male’s large and feathery antennae is to detect the females pheromones. This is the natural biological world functioning as it should, but I still find it so interesting and extraordinary!
Jane opened the door for the males and in the morning, discovered the female and one of the males mating. They stay coupled together for about a day. The female will begin to oviposit eggs almost immediately.
Polyphemus Moth cocoon. The hole at the end is from where the moth emerged. The cocoon is constructed of leaves wrapped around a cushion of spun silk. In the photo you can see the leaf structure and silk.
