Argiope trifasciata

San Jose Spider
I found this spider in my back yard in San Jose, it’s very pretty but a bit scary for me. Can you tell me what it is? I hope it stays outside and doesn’t try and get inside now the days are cooling down.

Hi Carolyn,
You have one of the Argiope Orb Weavers, Argiope trifasciata, the Banded Garden Spider. This genus of spiders is harmless, though might bite if provoked.
