I have pupated 5 swallowtail caterpillars, the first two sometime in mid-July. One, the very first one, has already hatched, about a week ago, but the rest are not hatched, and the pupae do not change color, although they move. I keep them in the dark, although they are not attached to a twig, but just roll along the bottom of the jar, one only attached which slightly changed color. Does this mean that they are sick or infected with something? Or is it possible that they will be released soon? Karelia.

Last year, one pupa saw that wintered, though pupated in mid-August.
Now it's hot, about 15-17 days have passed since the day of pupation, and they haven't even changed color

They change color depending on the place where they pupate, i.e. on a green plant, the pupa will be green, on a dark one-black and white, or if the pupa is ranging, it will most likely be gray, although not all. They will not change the color for a day or two through the shell of the pupa, you can see the color of the butterfly's wings. And since you keep them in the dark, they can fall into diapause. Attach them to twigs otherwise if they come out they probably won't spread their wings!

Thanks! I could see the color of the wings of the first butterfly that appeared through the shell, but I didn't see the appearance itself. Now I will keep them in a bright place, they were lying on sawdust, so, apparently, such a light green and yellow color.
And how can they be carefully attached to a twig, otherwise I didn't really succeed?
One caterpillar, too, was different from the others. There were small, black spots all over her body :

It has pupated, there are no spots on the pupa, it moves, it is alive in general. It would be interesting to know if this is such a disease, or is it related to something else?

still a picture, but it's not clear, and so you can see it

What's there to see?

Just that it's a caterpillar, not anything else. The light longitudinal strip is visible. Ilya, there are many hundreds of caterpillars, and to determine them, you need pictures of if not excellent, then at least good quality.

I don't see a pupa in the photo, but a caterpillar. The photo is not very good, but you can see the caterpillar, not the pupa. If you've had it for a month, then of course it's dead.

- The question would be on the pupa obtained from the caterpillar that is in the picture.
"You're wrong about the caterpillar not being able to stay safely for a month. The caterpillars of some scoops before pupation diapause (lie motionless) for several months, and even six months.

So to extend the caterpillar stage, should the containment temperature be lowered or raised? And to what approximate limits?
------------
Lower it.
Lower limit +10 +12 S
Optimal +18 +20 S

If you put +4 +6 C in the refrigerator, then
the caterpillars will not actively feed.

The question was not how to extend the caterpillar stage by itself, but how to extend the active feeding stage of the caterpillar in order to obtain the largest imago specimens possible.
