Remember those black widow egg sacs we collected a few weeks ago? Well, the spiderlings have hatched, moulted once, and are now emerging from their egg sacs!
Here is what an egg sac looks like when it is ready.
And here, with light penetrating the silk, you can see the spiderlings inside:
A spiderling peeking out.
And squirming free.
Here, the baby spiders socialize at the playground. They are best of friends at this stage…
Just kidding! They cannibalize each other like zombies!
In other baby spider news, at the apartment, the cellar spiders have hatched, and are spending some time adjacent to mom in the same corner where they were brooded.
