Northern VA, little black tube egg cluster on garden chair

we just uncovered our porch furniture after winter. they look like little dark anemone tubes. fingernail for size comparison. the closest thing i found with research is the north american wheel bug, but they aren't similar enough in my father's opinion and we usually don't see any in our area.

who decided to leave their babies on my porchstep? i need to contact them for child support payments. thank you in advance 🫡
