Mr. Muffet has flipped onto his back. This surprised me, because even though he refused food last week (something he rarely does), he just molted three months ago. I hope he does not mature yet with this molt!
Enclosure for Muffet, my Chromatopelma cyaneopubescens sling. (Three months into his new home, and he has already built elaborate silk tunnels under the leaves.) He often stands motionless in this spot on the edge of his web, waiting to ambush prey.
