The baby black have a similar shape as the adult, however there is a vast colour difference. The immature Widow Spider is much smaller than the adult and is yellow/brown in colour. The characteristic hourglass marking on its back is yellowish and not red. It is only after maturing and mating that the female spider takes on the sinister black body with red hourglass colouration on its back. The young juvenile black window spider does not have any red markings.
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.
One thing is they have an red hourglass's symbol on their abdomen. (Most female black widows have that, but not all.) They are found on almost every continent including this one (North America if you live here).
a red back looks almost the same. But doesnt have an hourglass shape. It has a red stripe on top of its abdomen.
They are similar to the black widows but they do not live in north america with black widows but they live in australia
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.
