Polyphemus is the largest giant silk moth in the Pacific Northwest. They can also be found throughout the contiguous United States. Coming in a variety of brown tones, the adult moths are known for their distinctive dark eyespots and graceful grey and pink markings. You can read more on this blog post about why they're one of our favorite species.

Polyphemus caterpillars get HUGE. They start off as tiny, adorable green caterpillars and grow into giant, adorable green caterpillars with yellow tubercles. Be prepared for the caterpillars to eat a LOT! They need a tremendous amount of mass and energy to metamorphose into giant moths. Not only that, but they won't eat as adults (having only vestigial mouth parts), so they rely on stored body fat for the energy that the males need to find a mate and the females need to produce eggs. 

General Directions for working with eggsRaising Caterpillars From Eggs

This species is fairly simple for beginners.  Keep in clean conditions, replacing host plant every few days and remove frass from sealed rearing container.  From the third skin shedding onwards, rear on cut hostplant in water and an airy pop-up tent or outside conditions sleeved on live plant to prevent disease.  (if rearing indoors in pop-up mist daily)  Make sure you have a good supply of fresh, pesticide-free food (list below).

Item Details:

  • You will receive ten (10) or twenty (20) Polyphemus Silkmoth eggs per order
  • Eggs will hatch about 2 weeks after they are laid by the female.  
  • We guarantee shipping you live eggs, and check for egg fertility by keeping some reserve ova. There are no other guarantees.  Transit and caterpillar care risks are assumed by the buyer.
  • Make sure that your mail arrives in a cool location, or that someone is there to meet them on arrival.  (Eggs can cook in the sun, and we only refund if our reserve eggs don't hatch)
  • If temperatures in your area are expected to be over 85F, protect your eggs in transit with the insulated box and ice pack shipping option.  
  • Caterpillars will need plenty of leaves to munch on after hatching.  There is a long list of possible hardwoods leaves that they may accept.  (See truncated list at the bottom), and make sure to have several options available and see which leaves they choose.  Here, we raise them on Willow, but they accept many hardwoods.  Oak is considered a universal host plant for them.
  • If you have additional questions, please email.  We will do our best to reply to questions as time permits.  Please be patient, as we're busy rearing large quantities of hungry caterpillars all season, and sometimes will be out collecting for days at a time too. 

Possible hostplants to try:

Oak (best choice if you have only one choice)
Birch
Alder
Walnut
Willow 
Apple
Bittercherry
Wild cherry
Chokecherry
Maple

      Almost Indestructable.
      Style: Squirrel
      We have an aggressive chewer that has yet to be able to crack this one open.  It's so indestructible that ours gives up on it and only plays with it infrequently. So the minus 1 star is more about the dogs preference, maybe.  But make no mistake, this is made better than any other toy I have ever seen.

      Fun toy for the dog
      Style: Squirrel
      This is a hit with our dog.  We have a schipperke who is very active and we play tug of war with “duck” every morning.  It has held up amazingly well despite his sharp teeth.

      “ Not easy to destroy”. My arse!
      Style: Squirrel, Style: Squirrel
      Description says not easy for aggressive chewers to destroy. Well, my non aggressive chewer had in destroyed in less than 24 hours. Notice the lack of feet. Think I can get a refund?

      My T-Rex Killed It
      Style: Squirrel
      This toy would likely be fine with dogs who don't immediately destroy toys. I have a small 15lb dog that I refer to as a T-Rex. We did not use it as a tug toy and it was taken away most of the time he wasn't playing with it, but I forgot about it for 5-10 minutes and it was torn apart. My dog does not get 'regular' toys any more. They have to be the toys marked for 'aggressive' chewers. Some GoDog toys have been good, and he has received the Bark Box toys for aggressive chewers, but Bark Box toys for aggressive chewers seem to only come in larger sizes if your dog is an aggressive chewer and a lot of the toys are too heavy and large (mouth size) for him play with very much.

      Sturdy: Westie tries to destroy it, but it has held up
      Style: Squirrel
      Because it's not a stuffed animal toy, there is not the issue with the stuffing getting torn out. Squeakers at head and tail. Dog loves it. Had fun lightly tying it onto fishing line, putting on the roof using the fishing pole, and yanking it off when the dog isn't expecting. He loves it and goes mad trying to, well, exterminate the varmint! Key is lightly tying to fishing line using a loop so it comes off (most of the time) when the dog shakes it violently. Short vid of how it comes off the roof. No dog in video because couldn't manage fishing pole, camera, and dog at same time. Have put it in bushes, low tree branches, flat in the yard...just start reeling in and the fun begins.
