INCREDIBLE! I'm not a spider
INCREDIBLE! I'm not a spider person per say? But this beauty is just amazing! Great photo!

I stumbled upon this one by accident.

I believe
this is a female.
The slender palps and large abdomen say that.

That was my original thought too, but according to the guide the coloration and size matches the male profile. I am willing to change it, but first I need more information to justify it.

Male widows and most spiders
have rounded "boxing glove" palps for mating.
Also, their abdomens are not swollen like balloons. Look at the images
for male spiders on the guide and info pages.

As to the markings, they are variable, but this specimen could be immature.

Change if gender...
I have reread the guide page and a few out side sources and I think you are correct. The palps do indicate a female. That being the case this would have to be an immature female based on the coloration. Thanks for bringing it to my attention.

No problem.
I noticed your picture because I had just photographed a male Northern Black Widow on my porch and was trying to decide which species it was.
