Thread: False Black Widow in St. Louis MO?

    False Black Widow in St. Louis MO?

    I'm pretty sure it's not a real Black Widow, which is why I first captured it.
    Found it on my wall at about 2:30 in the morning. Is it safe to release it outside?

    Hi cjmemay,

    Welcome to the new forum! (...and apologies for the rather late response!) You are absolutely right, this is one of the "False Widows" in the genus Steatoda. As you probably noticed, it does not have the bright red hourglass shape on its underside like a real black widow does. Yours might be Steatoda borealis but I can't tell for sure without seeing what the top side of her abdomen looks like. (There are more than one species of Steatoda in MO.)

    You can release her safely outside, just try to find a sheltered place if you can. In nature, they like crevices and spots under rocks and stuff.

    Hope this helps, thanks for posting!

    You're welcome. Thanks for releasing her rather than squishing her!
