Is this spider poisonous ?
Hi, no. It appears to be a Furrow Orbweaver, Larinioides cornutus. Almost all spiders have venom that they use to kill their prey. Some venom can be harmful to people. Those are the spiders that people call, “poisonous.” There are very few species like that. Unless you have a known spider venom allergy, spider bites aren’t a danger to worry about in the Grand Scheme of things. 🙂
