When anyone poses the question, “Is my ___ in pre-molt?” We can link to this with the caption, “If it looks like this.” Isn’t this textbook though? Little round mat, all spread out ready to jump into the new clothes. Doesn’t get anymore pre-molt than this. BTW: little G. rosea.
She-Ra, a mature female Kukulcania hibernalis (southern house spider) I've had for over 7 years, was hopelessly stuck in her molt. I wasn't confident that I could help her, because these spiders are so small and delicate when compared to tarantulas, and she had not even begun to extract her...
Eventually I had removed as much of the old abdomen as I could without tearing the delicate skin of the new abdomen. (I'm not sure, but there might still be trace amounts around the pedicel and book lungs.) Then I saw that one of her left legs was still encased in the old exoskeleton.
Having removed the loose, easy sections, I could see that some of the abdomen appeared to be stuck around the book lungs and epigastric furrow. I continued using the water dropper to try to soften and separate.
Next I turned my attention to the abdomen. She had made no progress extracting her abdomen save for a small opening near the sternum. I used the water dropper to fill the abdominal cavity with water and then backlit the area so I could separate the old abdomen from the new one.
First I worked on the two right legs that were stuck near the knee joint. I used my dropper to insert water into the femur tube as lubricant and gently pulled to free the legs. The first leg was easier than the second.

"Sideways Sally" (she is called that, because she normally sits with her butt facing out of the retreat) has been living in my house for well over a year. She had one brood of spiderlings last fall, and now she's made a second egg sac.
My A. bicoloratum decided to molt while I was sleeping. I can't wait to see how much bigger it's gotten. Maybe I'll be able to sex it after I get the excuviae.
Also, is there any way to make sure it's A. bicoloratum and not B. boehmei? I don't know if the seller can be trusted.
