Juvie female false widow moved another false widow's egg.

[Dragon Rescuer]

Hi,

I have been watching a false widow spider grow from hatchling to juvenile. She is approximately 6-8 months old. She is still in the escape proof baby enclosure. I put a (likely infertile) egg in the enclosure. The egg is from 1 of my other False Widow spiders. When I looked in on her, she had moved the egg sac over to her favorite spot next to her.

I didn't expect this. Does anyone have any idea why she did this?

See photo.

Thank you.

Fascinating. Have you looked up any peer reviewed articles on this behavior?

Not really. Was hoping you might. I don't personally have time to research peer reviews on all posts on here. I will stop all my daily activities when I need to research on of my animal's issues. This isn't meant to sound aggressive, just informative.
