Hi, I am trying to identify this spider that was in my backyard.  I searched the internet but could not find one that looks like it.  Would you be able to help me identify it so I can look up information about it.  I will attach some of the pictures that I was able to take.  Thanks in advance for your time.

Answer
Hello Tatia,

Great photos! Try searching Cross Orb Weaver (Araneus diadematus) and looking at photos taken of these from your state. You can find some more info here:

These spiders are non-aggressive, their venom is not considered to be dangerous for humans, and they are lovely to look at! Great find!

Best,
Jessica
