I have had this big spider living outside of my front door for over a week and then tonight I saw the red hourglass marking and thought it may be a black widow, but as seen in the picture it is not completely black. Is this still as dangerous as I think? Thanks,
Black Widows are often not black until they attain adulthood. This Black Widow is immature or a male spider.

Thanks to a comment from Genus 2.0, we now agree that this appears to be an immature Brown Widow.
