Ceanothus Silkmoth Cocoon -- Hyalophora euryalus

****Sold out for 2023.  Available again in November 2024

****Shipping to OR and WA, with more states expected for autumn time 2024.

This is the second largest giant silkmoth in the pacific northwest.  Caterpillars get huge, feeding on a variety to broadleaf and conifer 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 Ceanothus Silkmoth cocoon, inspected for quality and weight before shipping.
  • Cocoon is diapausing (sleeping through the winter for eclosion in SPRING 2024)  
  • 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 cocoons around May 1st.
  • Again place cocoons in pop-up tent on a layer of paper towel.  Mist daily.
  • Cocoon should eclose (hatch) in 3-6 weeks.
  • There are many resources and online groups to handle questions about live silkmoths and pupae care.  Send us an email if you get stuck :)
