Did you know there are 6 different types of Black Widow spider?
Yep, there sure are! Luckily only two types can be found in the Americas. Unluckily, one of those types were found in my front and back yards.

I'm no stranger to clutter. I have clutter in my home, I have clutter in my yard. Not cars on blocks type of clutter but I have things that likely belong in storage that ended up outside. Even though I thought I kept things neat, orderly and bug free I was WAY off base. My husband found the first Black Widow spider around the stairs leading from our back door. It was very small, likely not bigger (body wise) than an eraser on a pencil. It certainly had the red hourglass though. That red hourglass symbolizes that not only is this the most venomous spider in America but that it's the female of the species.

The male Black Widow isn't black at all but usually a brown color, as are the adolescent widow spiders. The one my husband found was likely an adolescent and had not yet laid an egg sack. I found another a couple of weeks later by our front stairs. The spider didn't build her web in any sort of hiding spot but rather out in the open. It was only a tad larger than the other spider but still was certainly a Widow. Just the other day I found yet another of these spiders but it was under some vehicle ramp equipment we had outside of our home. This Black Widow was (body only) around the size of a dime. Her web was large and had no distinction other than a cobweb. There it was on the side of the web, her egg sack. Her body long and black with a shiny back and stomach, a red hourglass on her abdomen and a red dot on her bottom. My husband made short work of her and her unborn spiders, but what about others? I'm afraid to even let the kids play outside. Why is that? Because I grew up on a farm where my family always said "a bite from a Black Widow is as poisonous as a bite from a rattlesnake and it will kill you". Is that true? Only partially.

Something else fancy about black Widows (and brown widows). Their webs, yes are cob webs, but they have a Triangle form. The top of the triangle feeds into the widows "funnel", where she usually hides in the Day.

Black Widow spiders eat any bug or insect unlucky enough to get caught in its web. One of the many I've found here (2 more last week...I think they're breeding under my home) had a dead June Bug fall from her web. Funny lil story about the June/May bugs here: http://www.knottsislandonline.com/nature/insects/junebug.htm
