A successful molt of Acanthoscurria geniculata

Yesterday, I noticed that the Acanthoscurria geniculata female tarantula I keep was upside down, molting. This is always a critical process, when a spider breaks out of its old exoskeleton a lot can go wrong. Case in point: last Saturday my female Monocentropus balfouri was upside down as well, but after a few days it was clear she was stuck in her molt and had passed. I had bought that spider back in April, 2026 so I was quite sad that it already had died in my care.

Today, I checked on the tarantula and noticed that it had molted successfully. In the above photo you can see the cast-off exoskeleton in the top half of the picture.

Originally a birthday present for Jaiden more than six years ago the care of the tarantula had shifted to me.
