Comments & ID Thoughts

Found this at 11:30pm in my bedroom underneath my desk.

This spider is brownish tan, like the variants of colors one can find in wheat. It’s body (not including legs is about half as long as my pinky’s first digit. As you can see it’s leges are quadruple the length of its body and it is sitting in the center of its web.

It seems like the thorax is pulsating. Does that mean this spiders pregnant? I don’t want to hurt it but think I should def move it outside or put in a quarantined terrarium and feed it regularly.

I think it’s a daddy long legs? But not sure. Halp?!

Since the females can get really huge with lots of developing eggs, it is very good that the eggs aren’t fertilized and start growing more internally. Having that development take place outside of the body allows… Read more »
