Can you tell me the name of this spider? Is it poisonous?
This is an orb weaver, likely Neoscona crucifera .
Orb weavers will never bite you, unless you manage to press against their bodies somehow. If you disturb them, they’ll scurry away or drop to the ground and likely play dead until you’re out of sight. If you should ever get bitten by a spider like this one, the pain would be mild and soon go away , without any need for you to get medical treatment.
