    Awesome pics, thanks for making a sticky for this one. Now if I would chill on the Invert spending and invest in a digicam then I would be able to show off my babies.

    That link is nice and all but I have seen adult L.hesperus females look like just about all those examples...color patterns vary greatly within the same species and should not be used as the sole means for identification method to differentiate between two similar species.

  11. very true, although the dorsal and the ventral combined eliminate possibilities of one or the other sometimes. You also have to remember, latrodectus are cross-bred between the different species, too, so that can make things even trickier. The site I was linking was just for those who don't know much about the latrodectus, a way for them to get a generally clearer idea. There are always exceptions to anything.

    Eggsacs are the best known method of identifying Widows of North America. The variations on dorsal and ventral markings are amazing and sometimes bizarre. Get this I found a Black Widow yesterday, in my OWN backyard, with a swirly olive-colored abdomen with a complete ventral red hourglass, and small dorsal markings resembling faint light red diamonds/tear drops, and the cephalothorax and legs are black as pitch. Never saw anything like it before. My prize Western Black Widow if that is indeed what it is.

    S Hourglass,

    I was aware of that I just wanted to point out that color at many times in inadequate for ID...especially where the ranges overlap.

    why do you get nervus As a ctreature they are very shy and will more then likely run to the nearest dark crevus they can find, unless of course you are pinching them trying to rip their legs off or smushing them they will mroe then not bite you in those insadinses.

    Simply due to the toxicity of their venom.
