Polyphemus Silkmoth Cocoon -- Antheraea polyphemus

***Overwintering pupae.  Keep cool on a natural light cycle, and fridge per overwintering blog instructions at Thanksgiving.

****SHIPPING to ALL 50 States.  USDA permits not required for this species.

This is the largest silkmoth in the pacific northwest.  Caterpillars get huge, feeding on a variety to broadleaf trees.

Adult moths do not feed.  Instead they live off their built up energy reserves from the larval stage.  Because of this, the moths only live about 7-10 days after hatching in spring.

Item Details:

  • You will receive one Polyphemus Silkmoth cocoon, inspected for quality and weight before shipping.
  • Cocoon is diapausing (sleeping through the winter for eclosion in SPRING 2021)  
  • We guarantee shipping a live cocoon.  Because this is a live animal, there are no other guarantees after shipment.
  • We recommend ordering two (2) or more cocoons as occasionally one won't make it through winter/fridge.  This is rare, but does occur in nature from time to time.

General Directions:

  • Keep inside in a pop-up tent/rearing cage (also available on our site), on top of paper towel.
  • Mist every few days, as inside air is quite dry. 
  • Around Thanksgiving/End of November, place cocoons into a sealed container and into the refrigerator.  (It's key to do this before winter solstice)
  • Keep in the fridge at approximately 38F, venting monthly for a few minutes and removing any visible moisture.
  • Remove from fridge in spring, and 3 weeks prior to the natural flight of this species in the region.  We typically remove Polyphemus cocoons around June 1st.
  • Again place cocoons in pop-up tent on a layer of paper towel.  Mist daily.
  • Cocoon should eclose (hatch) in 3-6 weeks.
  • Wild release
