Orb Weaver Spiders in the USA
Orb weavers are a family of spiders that spin large orb-shaped webs. Their webs catch small flying insects. Orb weavers are active at night and can often be found around human constructions. Especially, if you have a light on your front porch that attracts insects in the evening, orb weavers may consider that a good spot to build their web.
The bite of an orb weaver is not dangerous for humans and can have similar symptoms like a bee sting at worst.
