Greetings! I don’t often have anything to post, but here’s some shots I took this morning of a black widow spider that lives in a crack in the brick mortar outside the front door of where I work in Garner, NC. I noticed the web some time ago, but couldn’t tell what was in there until it came out to ’web up’ this rather large meal of what I believe to be a Bess beetle. Sure do hope it doesn’t decide to come inside!
I apologize that the one pic of the front came out so blurry, but I had to put the camera down on the ground to take it & couldn’t see the screen. I included it anyway to possibly help identify age, as I know the spots on the back mean it is younger.
Really enjoy checking out your site, and have had many chuckles over some of your replies to those ’challenged’ posters who don’t quite get the spirit of your site. Rock on!
Signature: thank God for macro lens

Black Widow Eats Bess Beetle

Dear tGfml,
We are really impressed with this incredible Food Chain documentation.  We agree that the prey is a Bess Beetle, one of the few insects that actually has family values where adults care for and feed larvae.  Both adults and larvae are capable of making sounds by stridulation and it is believe that the sounds are a form of communication.  BugGuide has a very informative page devoted to this family of interesting beetles.  When the Black Widow matures, she will lose all of her red spots and only the red hourglass marking under her abdomen will remain on her otherwise glossy black surface, making her a strikingly distinctive creature.  Black Widows are shy, hiding by day, though they can often be found in the open in their webs once darkness falls.  Though they are not aggressive spiders, readers should treat Black Widows with respect as their neurotoxic venom is quite potent.  Again, BugGuide has a marvelous information page on Widow spiders.
