@Ambilobe70 The elaborate patterns on the worms you featured in the first set of pictures don't mean anything as some silkworms have more markings than others in the 2-4th instars. HOWEVER, the picture of the dying ones in the box with the egg carton is definitely a disease. I think either...

My initial thought was disease as well. Once one gets sick, it spreads through excretion. Sometimes a few just die for unknown reasons and no one else gets sick. This year I had a lot of problems with stuck sheds. When it's larger worms, I can save most of them, unfortunately, it is a lot harder...

Thank You! Yes, if the eggs turn dark in three days, they can go in the fridge. If not, they will hatch. If you don't want them to, you can cull the eggs by putting them in the freezer.

Yes. The mulberry silkworm has three groups defined by breeding patterns. This has nothing to do with being zebra, regular etc. It has more to do with where they came from. The ones from European sericulture are univoltine; meaning they have just one generation per year then the eggs go dormant...

Hi, so I've been raising silkworms since 2020. Usually I place the mating pairs in a container lined with towel paper or wax paper. It's probably best to put a lid and some kind of ventilation. They usually stay put but I have had some climb out and wander off. You don't have to worry about...

Hehe! Nah, you're not weird for liking silkworms! They are fascinating creatures all on their own. I really love caterpillars, and that love brought me to the silkworms. Raising silkworms has led me down a path of learning about moths in general and taught me to appreciate them.

Hi MissSkittles! Thank you for your reply. I don't have a chameleon, I just raise silkworms. I've been a member here for years because this site is a great resource for learning to care for them and find other people who have silkworms. Hehe, I've been lucky most of the times where I end up...

Hi, ok so this is probably an unusual request. I'm looking to buy any newly-cocooned silkworms who have started that process around the 19th of January or so. The reason is because I bought a small group of silkworms of which most members were shedding and cocooning at the same time, except one...

Mine prefer the toilet paper rolls the way you have placed them. Some of them choose different places even when the rolls are available. I usually have these in a separate box and move those who have entered the pre pupal stage when the moment arrives. As for temperature, well I'm in Canada so...

Yeah, I read that the conditions the mother experienced while in her egg determines whether or not her eggs go into diapause. If the eggs turn black after three days they are in diapause and require cold storage. However if they don't go dark in a few days, they may be non-diapausing and...

Oops, sorry I forgot to answer about the container size. To that I would say it depends on how many silkworms you intend to hatch. When they are in the first three instars, the containers don't have to be very big, however once you get into the last two instars, they'll need more space...

Well the reason that some eggs don't go into diapause while others do has to do with the strain of silkworms we use. There are some that are univoltine, meaning one brood per year, so they always have diapause eggs thinking that the eggs will have to overwinter. There are also bivoltine and...

Here's one of the diapaused eggs just before hatching. Notice the color difference between this and the above.

It's ok to breed silkworms without prior experience, everyone begins that way. I'd just say that it is important to learn as much as you can about the process as you can so that you are well prepared. Well I've seen it only on eggs that do not go into diapause. Also, I am using a video...

Hi, so I just felt like adding my two cents here. I've been raising silkworms since 2020. I've also read alot about the topic. Mating can be from several hours to about a day. I've seen both. I've read that a female can give between 300 - 500 eggs, although other sources have cited different...

What are you going to do with them?

The egg in your last picture doesn't look good, either. I wouldn't "keep them cool", they need at least room temperature to hatch. I don't think they're going to hatch seeing as how there's not even one baby after over a month. I'm sorry 😢

Hi. Often silkworm eggs go into diapause during winter, but sometimes they don't go into diapause at all and just develop and hatch. It's determined by the conditions the female experienced when she was an egg. It is a normal occurrence and when it happened to me the first time, I didn't expect...

Hello everyone. I am hoping that you guys can point me in the right direction of a supplier who ships silkworm chow to Canada. I'm getting fed-up of the unreliability of the local pet shops. Too often they haven't got any in stock. I figured I'd try to get the powder and mix it myself. I...

I wish you lots of luck.
