When I checked the smallest of the scorpions I found last Saturday, I first thought it was dead. But on closer inspection it was molting. It was still for a part in its old exoskeleton. I was a little afraid that this one, like the Centruroides gracilis some time ago, might stay stuck with its tail. But when I checked later it was completely out of its old exoskeleton. A perfect molt.
In the above picture you can clearly see how the little scorpion got out of its old skin. The size of the scorpion exuvia is about 1 cm from head to tail. My best guess is that the scorpion is now 3rd instar, meaning it has molted twice now.
I used the UV LED scorpion detector I made some time ago to take a picture of the exuvia under black light. Since my camera is quite sensitive to UV (black) light I had to edit the above picture a bit, also to get the color close to the actual color of the light emitted by the cast-off skin (fluorescence).
