Keeping and breeding of beetles

to Guest
could you post this PDF online?

Perhaps the beetles just eat the eggs. When there is a lack of protein, many captive species do this. My aurats were fine without additives, but I didn't keep them for long - I only got 1 generation. I didn't notice any special difficulties...
Try adding yogurt to your food or buying protein-based food from Taiwanese, Japanese, or Germans and Czechs.
I won't say anything about the sex of the larvae - I don't know.

Recently found under the bark of dry mulberry logs larvae, some kind of barbel, the question is, is it possible to grow a beetle from these larvae at home? And if so, how to implement it? While they are lying in a liter jar with a piece of wood of the same mulberry, when you touch them-then they start to move, and so they got under this piece and sit there constantly do not eat, maybe you need to drill a hole in this piece and stick the larva in the hole()?

If the larvae lived under the bark (on the border with wood), then you can fold a couple of pieces of bark with the inner sides to each other, making depressions for the larvae. If the larvae were in the wood, then take a piece of wood, drill, stick the larva and plug the hole with a piece of wood to maintain humidity. There will be no 100% guarantee of withdrawal, but there are chances. I have recently bred a small wasp squeaker (I have been lying at home since June) and Herbst's chlorophorus (since October), although the latter did not spread the elytra...

I've read something here on the forum, and with the help of new information... So here's what I did:
1. The larvae themselves:

2. I built something like a "house" for them, for this I took pieces of the bark of the same mulberry, laid a thin layer of wet and soft bark on it, then put the larva on it, then again a layer of bark, then I cover it all with the second half. (Only I have suspicions that she will want to get out of there... () Well, in general, you can see everything in the photo







The result was 3 houses:

Please look at my ideas with a professional eye and tell me what's wrong Thank you)

it is advisable to fasten pieces of bark by wrapping them with tape or piercing them with pins at the corners...

Is that so they don't get out?

And so... My pets still got out of the "houses" and went to the bottom, though not all, and there in the dust and fine bark made, as it were, a small nest (maybe I just think...) Are they going to pupate, or are they just waiting to die?

Martix, I would put crushed bark on the bottom, a layer of about 3 cm, and put the whole bark on top. And probably it is necessary to moisten, but somehow so that mold does not grow.

While they seem to be feeling fine, I'll see what happens next...
