it is a black widow. it is all black becausse only female black widows have the red mark on their back. this means that is a male black widow.
AnswerIf it is predominately black and has the red hourglass on the abdomen, it is a black widow. It is my understanding that the stripes denote either a male or a younger female. I have also seen black widows with red dots on the back. The black widow with spots on its back usually has thirteen and it is called a European Black Widow.
It doesn't. It has the red hour glass on its belly.
A black widow. This spider is only a black widow if the entire spider is black, with a round-ball looking back-body, female variety if there is a red hourglass shape marking on the underside of the spider. From the top black widows are completely black.
No. The black widow is a shiny black with a bright red hour glass shape on its back.

You are probably defining a false black widow.
There are a number of black spiders with red on their backs. The most commonly referenced one is probably the black widow. But it is not the only one, and not all of them have red on their backs.It might help to note that the female black widow is mostly black, and may or may not have red (or red-to-orange color) on its "back" or the top sIde of its abdomen. (Viewed from the top or above, the female black widow is all or almost all black.) Some have a splash of red on their "back" or the top of their abdomen. Additionally, the hourglass that appears on the female L. mactans varies a bit from red to orange, and can be very dark in color. This characteristic mark is always on the bottom or ventral side of its abdomen.
