The mature female has a characteristic hourglass-shaped, reddish orange marking on the underside of the abdomen. Black widow spiders are predaceous, devouring small arthropods trapped in their webs. Their bite is relatively painless at first, but may be followed in about an hour by intense pain and swelling. The venom causes nausea, cramps, lack of coordination, and difficulty breathing by interference in nervous functions. Death has occurred in individuals hypersensitive to the venom.

Females are easier to identify, and sometimes males aren't even recognized as black widows. Males are smaller, and lighter in color. However, females are the only sex able to inflict the painful bite. Females are dark colored, around ?" long, with a bulbous abdomen. Luckily they have a red hourglass on their underside, which is made visible by the female's habit of hanging upside down from her web. Black widow populations are erratic, sometimes rising and falling dramatically over the years. They prefer to make their webs in dark, dry, undisturbed places. They are common underneath houses, in garages, or outside in woodpiles. Black widow webs are very irregular in design, not Read More Go to Site Alabama Cooperative Extension System Votes:0 Thursday, November 22, 2007 More Options if(navigator.appName=="Microsoft Internet Explorer"){ document.write(""); } else { document.write(" "); } About Extension · County Offices · Calendar · Publications · News · Multimedia Resources Alabama A&M University · Auburn University · Extension Units & Departments Staff Directory · Employment Opportunities · Weather · Related Websites The ACES IPM site is currently being remodeled.

It's poisonous bite can cause illness and severe pain, Deaths have even been reported. The deaths don't happen from the bite itself. The black widow got it's name, because the female sometimes kills the male after they mate. Scientists believe that only females are dangerous to people. The female has a shiny black body, and is only about the size of a pea and about 1 1/2 inches including the legs. The under-side of it's abdomen has a red or a yellow mark in the shape of an hour-glass. The male spider is only 1/4 as big as the female. The black widow's web is shapeless, and is made in dark nooks. | Home | Bolas Spider | Brown Recluse | Cellar Spider | | Wolf Spider | Tarantula | Pictures | Spider Trivia | Word Search | Recip Read More Go to Site Black Widow Votes:0 Black Widow View 1 View 2 Latrodectus mactans Family: Theridiidae Size: 10mm (body) Date: 11/28/99 Comments: Disclaimer Return to the : Previous page Main Alphabetical Table of Contents Main Table of Contents by Family Main Table of Contents by Date Table of Contents for the Miscellaneous Images or visit the : Bookshop Guestbook or Links to other sites granylil@edumaster.net © 1997-9 Charles Lewallen Read More Go to Site black widow — FactMonster.com Votes:0 Home World & News U.S. People Word Wise Science Math & Money Sports Cool Stuff Games & Quizzes Homework Center Fact Monster Favorites American Indian Heritage Month Thanksgiving Say Thank You Advent Hanukkah Pearl Harbor Day Campaign 2008 Presidential Factfile International Space Station Most Polluted Places in the World Harry Potter Page Ranger's Apprentice NFL Team Profiles Fact Monster Blog!

But females are the most treacherous of the black widow spiders. Typically black, the body of female black widows is approximately one and one-half inches long, including the legs. The female back widow spider can be identified by the red hourglass shaped marking on the abdomen. Male back widows are one-half the size of the females and lack the red hourglass marking.

The incubation period of the eggs ranges from eight to 30 days.

The adult female has a unique shiny black and bulbous abdomen and may reach a length of 1-1/4 inches. The smaller, 1/4-inch-long male is brown with red and white markings, including the abdominal hourglass design. This spider produces a neurotoxic venom 15 times more virulent than an equal amount of rattlesnake poison. Despite this distinction, only one death every five years in the United States can be attributed to this spider because few people are bitten and little venom is injected with each bite.
