Help, what is this?
She’s an Orbweaver, possibly a markings variant of Araneus marmoreus, a Marbled Orbweaver. She’s not dangerous to people. She should be outdoors do have a better chance to get food and water. She makes orb (circle ) webs that are strong and can withstand the force of being hit by large flying or jumping insects.
I agree on marmoreus, var. pyramidatus.
