Hi to everyone. Well, I'm having trouble with my Polythysana cinerascens pupae. I went out for two weeks, and left them in a small container with some water in the bottom -but not in direct contact with the pupae- to keep the humidity. When I came back, I noticed most of the pupae got or are getting red and hard, like if they dried. I don't know if it's an illness or they literally dried because of lack of humidity. What do you think? Please help, I don't want to lose all of them Here are some pictures (click on them to see the larger version): Here's a totally red pupa: And here's one that's getting red:

I don't know what it was exactly, I thought the skin was fragile and they ripped off, but maybe they had a runny bottom as you said. Thanks for your reply!

@joey: thanks for your very useful answer. Oddly, the first time I reared E. calleta, the third instar turned out to be the shortest (~5 days). On the other hand, when I reared Polythysana cinerascens, the first instar turned out to be the longest, as they took about 35 days to moult into L2. Well, just different experiences I guess By the way, what kind of genetic mutations could appear after many inbred generations? obewan: yes, the first time I reared E. calleta they took about a week in their first instar, that's why I found this odd.

Happy new year to everyone!
Well, my question is quite simple. My Eupackardia calleta larvae were born on december 28th, and on january 1st they already started to moult into their 2nd instar. That's 4 days, and I remember that the first generation of caterpillars took a lot more of time (more than a week).
I know that heat accelerates the process, but here in my room it hasn't been that hot (say, a maximum of 25-26 ºC or 77-79 ºF).
Could the fact that they were inbred have something to do with this? Thanks in advance!
