This summer I acquired a female
Centruroides sculpturatus as part of a trade. To the best of my knowledge, she was collected recently from somewhere in Arizona. She was assumed to be gravid -- she appeared very plump and a female collected in the same batch had already produced one brood.
Unfortunately, I do not have any photos of her at this point.
On the evening of September 2nd, she was found carrying a large pile of first-instars:
Young were estimated to number at 20.
The young on September 7th:
The young were observed completing the molt to second instar on September 9th, with most having completed the molt when this picture was taken:
On September 12, the second-instar young were still all on the female's back, with none wandering away. They did not appear to fluoresce at this point.
Young were observed to begin wandering from the female on September 15, though upon disturbance (such as removing a container lid) most scrambled back to her.
At this point the majority of young were removed from the female with a small paintbrush and she was separated to facilitate housing the young individually.
The final count of young was 26.
