Advertisement As I posted on this thread, my B. albopilosum (mature female, ~5.5" DLS) has taken to climbing on the underside of her enclosure lid. The lid is a solid piece of 3/4" particleboard, with 4 vent holes (1.5" diameter) that are covered with fiberglass screen. Feedback on my original post recommended that I eliminate the mesh to avoid any possibility of her legs getting caught. Honestly, I thought that was a bit overkill given the relatively small amount of mesh, and the fact that it is recessed and near the center of the lid, making it hard for her to get to. But I figured better safe than sorry, and made a new lid with smaller holes and no mesh. I was going out of town for a few days, so I decided to wait until I got back to put the new lid on (so any fumes from the paint I used could fully dissipate). The old lid had been in place for 10 months, so I never thought twice about waiting that extra few days.... When I got home and went to check on her, she was nowhere to be found in her enclosure. Upon close inspection, I found she had CHEWED A SMALL HOLE THROUGH ONE OF THE SCREEN VENT HOLE COVERS AND ESCAPED!! I was, and still am, in disbelief that my spider was able to navigate the underside of the lid to the middle, get her head into the recessed holes, chew her way through the mesh, and squeeze out! That's a pretty good trick for a creature that, from what I understand, is practically blind and has little or no intelligence! I was very lucky to find her almost immediately. There is a couple inch gap between the side of the desk that her enclosure sits on and the wall, and I had a hunch that she might be there. Sure enough she was there, huddled up in the corner. I was extremely lucky to find her so quickly, as I was gone for 4 days so I suppose she could have wandered off anywhere. Needless to say, once I got her into her enclosure, the new lid went on immediately (and is weighted down with a big can for good measure)! The first 9 months I had her I never saw her climb on the underside of the lid, or even climb on the side of the glass without some of her legs holding her up from the ground. She recently molted, just before the climbing began. Is it possible the molt made her feet "stickier", allowing her to climb where she previously was not easily able to?
