Spider eggs!


We’re currently cultivating 3 spider egg cases in the lab, with several more imminent, we think. This morning, I separated them from their mommies so I could put them in a temperature controlled incubator. I was delicate about it — not actually touching the sac itself, but tugging on the strands of silk holding them onto the web, and transferring them to clean vials. This one was a miracle, because without even trying I had accidentally and neatly removed the silken wrappings of the case. I don’t know if this is good or bad, since it might affect their development, but I guess we’ll find out.

These eggs were laid two days ago. Now we just watch them to see what happens next.

Also, don’t tell anyone else, but despite our care in maintaining all spiders in vials with a foam plug, or a larger container with closed lids, somehow babies are escaping, and we keep finding bits of the lab covered in webbing. Today it was the door to the incubator and the timed light. We caught the culprit for that — it was a tiny theridiidid spiderling who had built an elaborate web. We fed him as a reward.

I’m still hoping to walk in one day and find the entire lab cocooned in spider silk. My colleagues are probably not as eager as I am.

    Well, I do not see any reason to want a room totally in web but 60 or 70 percent does not sound all that bad. Spiders are great neighbors.
