My grammostola pulchra (about 2 inch leg span) was pretty active and jittery for a long time (since July I believe). His abdomen was nice and plump in the past few weeks as well. However, I’ve noticed that for the past week, he has completely disappeared under everything. He’s not in his hide; he upturned it and it’s on top of the substrate. My other tarantulas burrow in their hides which I know is normal, but my g. pulchra is completely gone. I don’t see any holes for breathing or anything. There are no signs of a tarantula having ever been there. I know he didn’t escape; he’s in there. Is this a sign of molting? Do I need to dig him up? Did he accidentally trap himself, or was it on purpose? I just want to be sure that he didn’t accidentally trap himself and will suffocate.
