Keeping and breeding butterflies

Gentlemen, Is it possible to grow a beech fork-tail caterpillar at home? I found it on a hazel tree, it seems to eat, but somehow not very actively.

Change the food every two days, or better yet every day. If placed in some closed vessel, then it is necessary to ventilate often, otherwise it will die.

Dear NIKSTER, I want to consult you about my Macrothylacia rubi. As you wrote to our brother in the KingSnake hobby about the vessel and feeding so that it does not die. Do you think it is possible to keep Macrothylacia rubi for additional feeding in such a container, periodically moistening the foliage? Or do you need more space?

This space is quite enough. I'd even put two more caterpillars in, so there's plenty of room and air .
Plenty of ventilation. The main thing is that the caterpillars do not escape through these holes
And the excrement will need to be removed as it accumulates.

and it will spend the winter in the caterpillar stage, and not pupa? Or did I misunderstand something?

Good afternoon again.
My pupa in the bank and hanging for a month))). The leaf has dried up, what is happening inside is not visible. I found information that Acronicta rumicis hatches 12-15 days after pupation. That is, do not wait for a butterfly already?

I'm glad she's alive, but could that be a bad sign?

It's just the pupae I used to have before...well, they weren't that active. So I don't have to worry too much about it?)

1. Disassembled the "collection" in the soil. Unearthed moth pupae. They are also actively twitching. It's good that they are alive-I understood from the previous answers)), but this does not mean that they are going to go out? In general, 10 days have passed since pupation, in theory they still have to spend the winter.

If not, is it time to send it to the refrigerator? Should I cover the container with napkins?

2. Does the raspberry cocoonworm overwinter as a caterpillar? Right? I do not have so many raspberry leaves)))

Two silly questions:
1. And if you do not clean up for the winter, can they hatch earlier?
2. Send the caterpillar to the balcony? She's still eating)))

Do you think it is possible to keep Macrothylacia rubi for additional feeding in such a container, periodically moistening the foliage? Or do you need more space? Initially, she lived in a large mesh cage with the ground at the bottom, but could not find the foliage and crawled up the grid and now in this small box began to feed. Do you think there is enough ventilation? I think Dear KingSnake will also be interested in this.

Gentlemen,
Please tell us what food is suitable for Macrothylacia rubi. Fed 2 weeks with a raspberry leaf, successfully, eats like an elephant and shits the same way! Now there is no access to raspberries, in the wiki (which I don't trust) it is written that the mass of plants???

I haven't used raspberries in a long time. It is better to use what grows on the ground.
You can use strawberries (Fragaria).

Well, yes, without wintering in the cold, few butterflies wait for spring.

There is a chance that one or more butterflies will come out, and most of them will go into diapause. Of course, if you do not store it in a warm place.

One hatched today! I don't know what to do now... From what so, prompt?! Too warm?

So, they already need to be put in the refrigerator?
We were standing on the balcony, 17 degrees outside the window. They put me in a room for one night (they forgot to take it out again). It was 26-27 degrees ...

And how to determine which pupae can be put in the refrigerator now, and which ones are already too late - butterflies will come out?

It's too late to hide the pupae. I'm afraid I'll have to wait until everyone comes out. What remains to put in the refrigerator or on the balcony.
