Apparently the momma spider will have laid these spiderlings’ eggs late last summer. She will then have doggedly stuck with them to protect them. Consequently, she will have starved to death last autumn as she couldn’t go out to feed. I’m sure she’d be pleased to see so many little spiderlings hatching out.
With the distinctive black triangle on their backs, these spiderlings don’t look very much at all like adult garden spiders, which tend to be mottled shades of browns, creams and black.
