A few are sold/spoken for already but there are plenty left, PM me if interested. The mom is a really stunning specimen, she's jet black throughout except for the "abdomen and of course the cool orange Nike "swoosh". This is definitely a fast species but they aren't that bad...mom is actually pretty mellow, except when taking her egg sac away of course...
....still sorting and catching slings. I feel like an assembly line worker.
So far just over 100 setup...by tonite I will try for the remaining 10-20 slings.
It's hard to tell because they all bunch up so in the cup so there are just these black and pink patches of fur.
I think I'm going to setup up an experimental communal tank with the last dozen or so. I'm still ironing out the details and landscape design.
i usually pull a little (slack) to one side and work it into layers a little at a time, then cut it with scissors (verry gently) untill i can take a look.
So...I haven't seen this adult female in a long while, the one who laid this sac. I decided to dig her out of her tubeweb fortress only to be surprised by the sight her her holding a fat eggsac... AGAIN.
YIKES!
Anyone ever have a double-clutch? I have no idea how old this sac is so I'm a bit hesitant to pull it...
Aww yes my friend... this genus is well known for double clutching.. right now im waiting on my P. cambridgei to drop her second sac. She is really really fat right now. she just started to build her webbing back up. After I took her sac last time she tore all of her webbing down and threw it across the tank. i thought this was a really cute picture.... this is her from last night starting on her new webbing.
When spiders double clutch, do they always wait until the first eggsac is hatched (or stolen!) before they drop the second one? Or do you get cases of a mother with 2 sacs at once? And if they wait, I assume they only fertilise half the eggs when they mate and store the rest until they are ready to lay the second sac?? That's pretty crazy, I wonder how they do that. And why some genera do it and others don't.
I have to admit, I really didn't "feed her up" after taking away her sac...just a few crickets here and there and she still made the second sac which is why I'm so surprised. I think I may have fattened her up so much for the first sac that she didn't lose alot of fitness afterwards.
Double clutching usually involves one clutch after the other, not simultaneously. T's put a fair amount of care into their sacs, not only guarding them but constantly turning and moving the sac to make sure conditions are optimal for developing slings. It would be hard for a single mom to care for 2 sacs and resulting slings at once.
I couldn't tell you why this species is prone to this behavior while others aren't but this genus must have some sort of adaptation that lets them use and store sperm accordingly. I'm sure there's literature on the subject.
I've heard of this species and of cambridgei double clutching. Usually though I thought the second sack was smaller.
Congratulations on the new sack!!! By the way the babies I got from you are beautiful and doing very well.
So, it looks like I jumped the gun a bit. I pulled the sac and they were eggs...but at least they look good so I decided to manually incubate them.
The pic in my initial post shows the mom holding on the first sac just before I collected it from her. This time around I swear she knew what was coming.
I pulled out her cork tube and she was positioned near the lower end of the tube. At first she turned to face me holding on to her sac with a look that was saying..."bring it on".
After she held this position for a few seconds while I snapped this pic she decided enough was enough and she called me out. She basically took a few steps back and put down her sac. Then she moved forward almost coming out of the tube as she pretty much used her legs and body to block off the entrance to the tube.
Luckily the cork bark tube has a slit in it and so I was able to distract her from behind while I pulled the sac. As I pulled it out she never kept a leg off it and she came out of the tube along with the sac. Luckily she let go and landed on the floor where I was working with her so it wasn't far. I scooped her up in a cup and put her back in. She's still quite angry but has resumed feeding.
I counted just over 100 eggs...not bad for a double clutch sac. They all look to be fertile.
