For the 4th year, I have Cecropia moth caterpillars (Hyalolphora cecropia). This is a male and female mating early this month. The male is on the left, with larger antennae (click the photo for a larger image). The female proceeded to lay many eggs, and tiny caterpillars have now emerged.
I plan to raise a few of the caterpillars – the rest are available to anyone who’s interested.
This is a collage of their life cycle.
David Britton has created a fascinating video of the Cecropia moth life cycle. It condenses 7 weeks into 13 minutes. If you’re considering raising a caterpillar, the video lets you know what to expect. Otherwise, it allows you to see one more example of nature’s miracles.
To raise caterpillars, you’ll need:
- A covered container that allows air circulation. I use a plastic box with netting.
- A good source of food for about six weeks. Some of my caterpillars are eating Red Maple leaves (Acer rubrum), and the rest are feeding on Wild Cherry (Prunus serotina).
- The caterpillars will eventually make cocoons that can be put outside. If you wish to see the adults emerge next May or June, keep the cocoons in a protected cage in a cold place through the winter.
If you’re interested in one or more caterpillars, please contact me. I’d also appreciate you sharing this blog with anyone else you think might be interested.
We would be happy to take some caterpillars off your hands, if you still have them. We are in Louisville.
Thanks!

Blair, I still have and glad to know of your interest. I’ll email you to see what we can work out.
Pretty cool!
I would love to raise some caterpillars of the Giant silk moths if you are still doing it and have any to part with.
Jess, Glad to now of your interest. I don’t currently have any moth caterpillars. However, if I get any in the near future, I’ll let you know. Hope you can manage to find some. It’s a fun experience.
We came across a caterpillar on the sidewalk the other day and moved him to a nearby garden only for it to go on the sidewalk again. My kids were concerned someone would step on it so put it in a bug container to bring to show their class. However overnight it made its cacoon. Should we leave it be or try to move it into the garden.
Tina,
Glad to have your email and glad your kids wanted to save it. It would be neat if you could identify the caterpillar so that you would know what moth is in the making. You might google Silk Moth caterpillars – I’m guessing a Promethea, Polyphemus, or Cecropia. The cocoon will likely overwinter and the moth emerge next late spring or early summer. If you keep it in the bug cage, it would need to be kept in a cool place so that it doesn’t emerge prematurely – possibly a garage, or porch. Or you can put it outside – maybe attach it to a tree limb. In that case, it will be vulnerable to outdoor predators – birds, squirrels, etc. The kids science teacher would also be a good resource of information and I can imagine he/she would be glad for the kids to bring it to school. Hope this help.
dear Betty, very nice to see your offer. live on LI in New York . cecropias used to be plentiful, now you don’t see any sign of them. am presently raising polyphemus and have done Lunas have and will let them go to procreate. would enjoy doing the same with cecropia. if i could acquire some of their eggs it would be most helpful. would have polys to trade this spring or would purchase the cecropia eggs.
Paul, Always good to hear from folks who raise moths. I’m sorry to say I don’t currently have Cecropia cocoons or eggs. However, I have a friend who might be able to help and I have forwarded your email to him. He might also have or know of another source.
Thanks for your email and best wishes.

Hi Betty! Raising butterflies has become something my grandpa and I love to do, and I’d love to try moths too, especially since there aren’t many in my area. I’m on Long Island, New York, and I was hoping you could send me the email of the friend you have that might be able to help me get some eggs or cocoons. Thanks so much for any help you can provide!
Arianna, I’ve sent your request on to my friend. I expect you will here from him. Glad to know of your interest.

My dad and I collected butterflys and moths in the fifties. I would love to have cecropia eggs to raise. I would think
twelve to fifteen eggs to get a male and female. — Kevin
Hi Kevin,
I shared your contact information with Web Barney, and I hope you heard from him.

Hi, we have a wild cecropia caterpillar in 5th instar with some black around rear end and what looks like a decoy eye – I’m worried it may be parasitisation though and don’t know if the wasps lay eggs in this species before cocoon is formed. It S crawling around in a shrub but is no in a short broken off stalk and if anyone knows if I can or should place it onto a better host tree or larger shrub for cocoon stage I’d be interested to know. I can send or post pics
Lorena, I’ve never seen anything like what you have described but it sounds suspicious.
