They can take 3 weeks to pupae!
I have about 5 in pupae right now and they've been like this for well over a month, maybe two. I haven't been keeping them warm or putting a light right on them, (experimenting)
I have a question, does it mean there is something wrong with them if they go into their pupae stage early? I fed the few remaining silkworm chow, mixed and made a solid (just like their hornworm chow) and they stopped eating not too long after without getting that huge size and pupaed (a few died) and they were only about 1 1/2 inches long compared to the huge hornworms that ate the hornworm chow. So I have like 2 small pupae's and 3 larger ones
