Found this huge thing tonight. I’ve never seen anything like it, it has considerable weight, it made a thud when we put it in a plastic container.
She’s an Orbweaver spider in family Aranidae. She’s big because her eggs are reaching maturity inside of her. She will soon oviposit them into an egg sac and she will shrink noticeably. I don’t give a more specific identification from her underside. She is not a medically dangerous spider. She sleeps in a hidden spot during sunny hours and builds a web next-to that spot to catch nocturnal insects.
