When I woke up this morning, I noticed my female Brachypelma emilia had begun to molt, upright. The last time she molted, she tried to do it upright as well, but I flipped her over to try and make it easier for her. This time, she seemed too far along and I thought flipping her over would do more harm than good. So I let her be and she seemed to do just fine. It went rather quickly and she toppled over to her side once she was out of the old skin.
You might see a dead cricket in some of these pix, I guess she just killed the cricket and didn't eat it before her molt. I took it out of her cage right after the molt to avoid the dreaded mite infestation.
