Silkwormswhat is this cocoon?
Hi I came across this cocoon about 2 weeks ago on the ground. It has been scratching on the inside ever since. I’ve determined it might be a polymorphous moth. Any thoughts? Also how long will it take before it will hatch? Thanks,
Ryan
Hi Ryan,
We are nearly positive that this is a Luna Moth Cocoon, but it might be a Polyphemus Moth. Without meaning to sound smug, it will hatch when it is ready. The complexity of insect metamorphosis is not like a three minute egg. Some combination of time, temperature, humidity, length of day, and perhaps airborn pheromones will trigger the hatching.

This isn’t a Polyphemus. My Polyphemus cocoons (sitting right next to me) are a bit rougher.
