Those people were right about that saturniid habitat! I was thinking it is a Polyphemus moth cocoon. Am I right? @NathanJBoob?
Good luck with that. Get a bio-med engineer to walk you through building your first containment. Expect to fail the first 3 or 4 inspections anyway.This can be a room in your house that is inspected by APHIS and meets certain standards for preventing the dissemination of plant pests.
Lol, on the neon luna! You never know what might pop up though!I was joking about a neon orange color morph (although it would be amazing).
I would love to have different color morphs in a giant silkmoth colony, but I first have to find the regular ones. So far, I have only ever found a couple of cocoons. I recently learned of a new place in my area that has large populations of luna moths, and I was told how to find the larvae. Do you have any tips for finding species in the Ceratocampinae subfamily? I know they pupate underground, but I have yet to find any larvae (except Anisota sp).
How do you supply enough fresh hardwood leaves to your larvae? The leaves quickly dry when I harvest branches despite me putting them in a jar of water. How can the leaves be kept fresh?

Looks like a poly to me!View attachment 300120

I’m sort of running out of synonyms for the word “amazing” Just a wuick question, but where do you find the cocoons? I know for a fact that giant slik moths live in my area but I have never managed to find one or a caterpillr yet.Lol, on the neon luna! You never know what might pop up though!
As far as finding larvae, the best time is at night with a bright led light. The larvae will be actively feeding and they kinda glow against the foliage. Knowing what food plants are preferred is a must as well. Luna in the northern US prefer Black Walnut and any of the Hickories. If you live where Sweetgum is common then that is a good one to search. I think finding subterranean pupae would be mostly by luck. Finding their larvae would be easiest at night with a bright led
headlight.
I do almost all my rearing outdoors in large mesh bags. I use mosquito netting and sew it into large bags. The bags are placed over the appropriate branch and the hatchling larvae placed inside.
Some species of host plant do better as a cut food than others. Walnut is almost impossible to keep from wilting. Cherry, Oak and Sweetgum branches keep for about 4 days if you recut the end of the branch under water after the first cut. That eliminates air blockage after the first cut and allows the branch to draw up moisture.

I personally rely on my own captive breeding to supply cocoons for my own purposes. I do collect some cocoons every year if I find them.I’m sort of running out of synonyms for the word “amazing” Just a wuick question, but where do you find the cocoons?

Depending on where you're at down there you may have Rothschildia cincta and lebaeu forbesi as well as Eupackardia calleta. These all spin cocoons right on their host. They are all fairly easy to rear as well.This is a super informative thread, thanks for that! I've been wanting to try my hand with saturniids again after botching cecropia larvae. I'll have to keep an eye out for border saturniids now and see if I can care for them. Might try black witch moths too if I can track down the larvae...
How long does it take for the larvae to eat through the leaves in the meshed area? Obviously faster for later instars, but I still figure the early instars would eat through it at a good clip. I'm guessing you don't have to worry very much about tachinids then with the mesh?
I've actually found some empty Rothschildia cocoons while visiting the Brownsville area, so those were really neat. Maybe this year I'll be able to get moths or occupied cocoons. They're pretty obvious in the trees once you know what to look for.Depending on where you're at down there you may have Rothschildia cincta and lebaeu forbesi as well as Eupackardia calleta.

I use smaller sleeves for hatchlings and tend to crowed them a bit at that stage. They don't really start eating a lot until they reach the end of the third instar. I usually split them up at that time and move them into larger bags. There are so many variables that determine how long it takes them to go through a bag worth of leaves. The first 3 instars is generally spent on one branch. After that I might have to move them once a week or at the end of the 5th instar, ever three days.
Tachinid flies are no problem in mesh bags, but sometimes different Ichneumons will get one or two.
Ideally they should be split up after the 3rd instar and moved into larger bags. Some species I tend to crowd a bit. Luna, io and maia larvae can be crowded as long as they have lots of leaves. Most others should be spread out as thin as possible.I've actually found some empty Rothschildia cocoons while visiting the Brownsville area, so those were really neat.

That makes sense. Do you split up the groups as they get larger, or keep them about the same with larger bags?
I didn't figure the tachinids would squeeze through, but I wanted to check on that since they can be a bit of a menace.
So I do have a poly cocoon I collected in the fall from a caterpillar. How do I get it to hatch? I know it needs to be kept cold but for how long? Also I’m so happy my one question turned into all this, I really want to get some native moths now.
I leave all my cocoons outdoors over the Winter so that they stay in sync with Spring leaf-out and the emergence of their wild counterparts.

Collecting at lights is probably the easiest way to find adults. Any females found will have already mated and laying fertile ova.How do you collect the adults? I would believe that using light traps at night would be the best method...
I had a bear destroy some bags years ago. It didn't really mess with the larvae though. The bags looked like they went through a paper shredder though! Squirrels are my number one enemy! They chew holes all over the bags to get to larvae and cocoons. They seem to target luna and polyphemus the most.Last year I had some animal (I suspect a bear or raccoon, both are in the area) tear apart three of my polyphemus moth bags and eat most of the cocoons and larvae. It left my cecropias alone. That's another issue to watch out for.
I imagine that cecropias and prometheas might be somewhat distasteful or toxic, given the bright coloration of the larvae.I had a bear destroy some bags years ago.

I don't think most metal mesh is flexible enough, and you'd be hard- pressed to find mesh fine enough to keep out parasitic flies and wasps.Is it possible to make a metal mesh that would be flexible enough? I would think that animals would not be able to chew through that.
