I remember when this story came out. Its complete and total BS, but a fun read none the less.
As far as the Black Widow is concerned, there is alot of false info in here. First off, if youve seen a "Black Widow" on your porch, fence, or anywhere else that gets sunlight then you didnt actually see a BW. There is a spider called the False Black Widow that looks almost exactly like it, and is very common throughout the US. Theyre all over the place around here and people always freak out when i pick one up lol. However, there is a good chance that many of you have come in contact with many juvenile female BW's without knowing it. Until they reach maturity they are a dark gray color with white stripes on its abdomen. Its also common to see very bright yellow, orange, or red spots on them. At this stage they rely on their bright colors to ward off prey, so theyre more confident going out into the sunny spots of your gardens or porch, etc. Their venom is fully developed at this stage, but their chericela(fangs) are too small to inject venom deep into the tissue. You might have a mild local reaction but it wont be bad.
I worked at a camp in Asheboro, NC back in 1997 that had tons of L. Mactans(Southern BW), which is the largest and most dangerous Latrodectus(sp?) species. Out of all the deaths from BW bites in the US, which are few, its believed that up to 85% of them were from the L. Mactans. Anyway, the NC Wildlife Dept came in to do a study of them, and i got to help them with tracking them down since i knew the camp so well. I learned alot about them, but the most important thing i learned is that 90% of the info on BW's out there is false.
Ive never heard of these spiders biting a person for no reason. I saw these scientists picking them up and handling them fairly roughly and none of them were bitten. The only time they bite is if theyre about to be squished...and even then theyll usually only bite if theyre carrying eggs, sick, injured, or weakened in any other way. Their bites are rarely fatal, but they WILL cause sever pain and have led to other life-long conditions(usually involving the liver and kidneys). My grandfather was bitten by one while laying a brick sidewalk(it was deep in the pile of bricks) when he was in his 30's, and he said it was one of the most painful things hes ever been through...and this is coming from a Bombardier who was shot twice in WWII.
The NC Wildlife eventually unleashed a hoarde of Spider Wasps that were bred specifically for tracking down and killing BW's and False BW's. This was the first state to use this method, and its being used in many other states now. Australia and NZ have started using a variation on this type of Wasp for controlling various deadly spiders in their homelands. The speed and effeciency of these Wasps is absolutely incredible. I saw two of them kill over 15 BW's in less than a day. This was in a controlled environment(tank), but it was still an amazing display of their abilities.
Sorry about the long post lol
