Many years ago I found half-grown caterpillars from the species, I reared them successfully on Trifolium repens.
The caterpillars pupate 1-5cm underground.

I would try willow (Salix) or alder (Alnus) if possible. At the moment I'm rearing my Actias artemis caterpillars on Carya, which is also still green.
I don't think Prunus laurocerasus is a suitable hostplant...Regards, Klaas

Overwintering Theretra alecto should be possible! In Damascus (Syria) it is very common and the average winter temperatures
in the city are below 7 degrees Celsius.Groeten, Klaas

Dear Jürgen,
Maybe this article can help you: http://redalyc.uaemex.mx/pdf/455/45513106.pdf

I keep them in the fridge from November until April at about 3 degrees Celsius, every now and then I take them out and I spray some water on them.
Under these conditions almost all of my pupae hatch in spring, however some pupae will overwinter twice! For example, from my breeding of G. isabellae
from eggs from Valais in 2009 I ended up with only a few male pupae. None of these pupae hatched this year... G. isabellae is a mountainous species, so
frost may be necessary for some populations. This summer, strangely, an adult emerged less than one month after pupation, without overwintering.Regards, Klaas

I don't know if 100 days will be long enough, but it's important not to keep the pupae too dry and below 5 degrees Celsius (the pupae tolerate temperatures below 0).
When you take them out of the fridge, it should take about 2 to 4 weeks until the adults emerge if you keep them at room temperature.Regards, Klaas

Manuel, 14 Grad wird kein problem sein: Actias isabellae - es geht auch anders...

A few of my (ex ovo) pupae produced a second generation and I got one mating. Yesterday was the first sunny day of the week, my 3 days old female laid 55 eggs in 6 hours time!
I'm keeping it in a 40x40x60cm breeding cage in my garden, with an infrared lamp. I try to feed it with a sugar solution twice a day. The female lays eggs on Angelica only and shows
no interest in Foeniculum. The reason could be that it was reared on Angelica, but this ignoring of Foeniculum may also have a genetical basis. -
Hoi David,
Misschien heb je hier iets aan: http://www.zmuc.dk/entoWeb/staff/Supl.Bol.MMF-09-2006.pdf
According to this article, both species don't occur on Madeira.Groeten, Klaas

Hoi Matteo,
Ik denk het wel, je kunt het gewoon proberen toch? (=I think so, it's worth a try.)
Groeten, Klaas

It's a male of Caloteryx virgo, this species does fly on Samos.

ich weiß nicht wieso man solch herrliche Falter per Handpaarung vermehren sollte. Leute ein Aerarium reicht vollkommen aus, die Falter brauchen Sonne und Futterblüten, wo sie saugen können.
Why not try handpairing if it is so easy (much easier than in G. isabellae)?
Remember that not everybody has an 'Aerarium' and there is allways a chance that with bad weather, the temperatures are too low to get a natural mating.
Another thing is that using hand-pairing, the male won't get worn.Regards, Klaas

Dear Sphinx,
At first I had only sexed them by eye and this lead to my false conclusion that most of the pupae were males.
Because it seemed to unlikely to me, I made close-up pictures of the end of the pupal abdomens and I found that they are very easy to sex this way.
Females have a narrow groove in the middle of the ventral side of the 2nd abdominal segment.
Now there are only a few pupae left of which I can't determine the gender, because they have very vague female characteristics.
I will post some macro pictures from Papilio machaon pupae in this topic as soon as I can.Regarding your last question, in only a few pupae I can find developing butterflies: their eyes are turning dark when you hold the pupae close to a lamp.
Best regards, Klaas

Jenny is right, it's Libellula fulva!

I think it's looking for a place to pupate, so you don't need to feed it.

Thank you very much for your help Sphinx!

The first 25 caterpillars have pupated. I just checked their gender and I have only 1 female! How could this be possible?
From some Lycaenidae/Nymphalidae species I know that the male adults emerge a few days earlier than the females, does anyone know
if this is the same in Papilio machaon?Regards, Klaas
-
Strangely, some days ago male from G. isabellae emerged. The caterpillar pupated only one month ago, I keep all of my
pupae at room temperature during the summer... -
Dear Stefan,
Please look here, this is the specimen that I meant (although your specimen also has reduced dark markings on the forewing):
