The attractant verdict
Four possible answers to why this species turned up. Three stay unlit — and that's the argument: the honest answer could have been any of them, and for this species it wasn't.
This is the most common answer in this hub — an answer, not a shortfall.
Common garden spiders want prey and a web anchor point — nothing else is going on.
Our own previous page said the common garden spider is attracted ‘mainly because of the availability of food, shelter, and suitable environmental conditions’ — accurate, if vague; we're keeping the substance and tightening it.
A stable anchor point for a large orb web — between two plants, a porch railing and a post, eaves near an outdoor light — positioned where flying insects are plentiful. Outdoor lighting in particular concentrates the night-flying insects these spiders rely on, which is why webs often appear near porch lights.
“Nothing about a common garden spider is special. It wants a place to hang a web and insects flying past it — a porch light does both jobs at once.”
Why it's here, in full
Why food and a web anchor point explain it
Common garden spiders build large, semi-permanent orb webs and rely entirely on flying or jumping insects blundering into the sticky spiral, so they position webs wherever two things line up: a stable anchor between two fixed points, and a steady supply of insects nearby. Outdoor lighting is a frequent factor, since porch and yard lights draw in night-flying insects that then end up in a nearby web; dense garden vegetation does the same job during the day. Neither of those things is a property of the house itself — they're properties of the yard and the lighting around it, which is why a web often reappears in almost the same spot night after night.
How to tell it's actually this species
Real signs only — a species with four honest tells gets four, and stops. Where a sign is weak on its own, we say so.
A large, circular orb web with a dense zigzag pattern of silk in the center, usually rebuilt in the same spot each night
A web anchored between two fixed points — porch railings, plant stems, eaves — positioned near outdoor lighting or dense vegetation
The web's owner sitting head-down in the center of the web during the day, largely motionless
