KidsHealth Kids Bug Bites and Stings What a Black Widow Spider Is The black widow spider is one of a few poisonous kinds of spiders in the United States. It is part of the arachnid family, which includes not just spiders, but ticks , mites, and scorpions , too. Its body is about one-half inch long (smaller than a dime), and it has long legs. The black widow spider is shiny and black with a red-orange or yellow mark in the shape of an hourglass on its stomach. Black widow spiders and their relatives can be found almost anywhere in the Western hemisphere of the world in damp and dark places. Their favorite places are wood piles, tree stumps, trash piles, storage sheds, fruit and vegetable gardens, in stone walls, and under rocks. If they come inside, they will go to dark places like corners of closets, garages, or behind furniture. They are shy by nature and bite only when trapped, sat on, or accidentally touched. What a Black Widow Spider Bite Looks and Feels Like A person who gets bitten by a black widow spider might not know it right away, since the bite can sometimes feel like a little pinprick. After 30 to 40 minutes, though, the area of the bite will swell and hurt a lot.

Envenomation by these spiders can be fatal to children and ill or infirm adults. Ordinarily, the body mass of a healthy adult is sufficient to dilute the venom to less than a fatal concentration. Spiders of the genus Steatoda (also of the Theridiidae family) are often mistaken for widow spiders, and are known as False Widow Spiders . The false widow spiders are significantly less harmful to humans.

back Spider Venom Spider Venom The Wound of a Widow While the black widow ( Latrodectus spp. ) is considered the most venomous spider in North America, death from a black widow spider bite is highly unlikely. Furthermore, black widows do not actively hunt humans in order to bite them. Latrodectus bites occur most frequently when the spider is trapped against human skin or provoked to defend itself. In the United States, no deaths from a widow spider have been documented for more than 20 years. Only the larger immature female and adult female spiders can bite through all layers of human skin and inject enough venom to cause a painful reaction. Small juveniles and all ages of male black widows are essentially harmless. The infamous western black widow ( Latrodectus hesperus ) is not found in the Seattle/Tacoma area. Its Washington range includes only areas east of the Cascade Mountains, a few San Juan Islands and a small part of Whidbey Island.

HGIC 2505 http://hgic.clemson.edu Poisonous Spiders of South Carolina Almost all spiders are capable of producing venomous bites. However, there are very few species of spiders in the United States and South Carolina that produce harmful bites. The U.S. Public Health Service reports that poisonous bites are a very minor cause of death in the United States. Annually, venomous animals produce death as follows: bees, 12; wasps and other hymenoptera, 10; snakes, 14; spiders, six; and scorpions, one. In South Carolina, two groups of spiders, the widow (Theridiidae: Lactrodectus species) and the recluse (Loxoscelidae: Loxosceles species) spiders, are of most concern and will be discussed in detail. Two other species, Chirocanthium inclusum (a common running spider) and Argiope aurantia (the black and yellow garden spider), have occasionally been reported as inflicting serious bites in humans. None of these bites produced death or prolonged illness. WIDOW SPIDERS Description: The widow spiders are large with mature females measuring 1½ inches with legs extended. Most people are familiar with the southern black widow ( Lactrodectus mactans ), a glossy black spider with a complete red hourglass marking on the underside of its abdomen.

Thomas PO Box 147100 Gainesville, FL 32614-7100 Venomous Spiders in Florida G. B. Edwards , Taxonomic Entomologist In Florida, only two main types of venomous spiders occur: widow spiders and recluse spiders Three species of widow spiders are native to Florida, and a fourth species has been introduced. No species of recluse spiders are native to Florida , but three species have been intercepted, and occasionally have established populations in single buildings at scattered locations. Both types of spiders tend to be found in similar places, which is in or under objects where their presence is not necessarily obvious. In the interest of safety, it is recommended that people engaged in activities where they cannot see where their hands are being placed (such as lifting boards or firewood, or reaching into storage boxes) should wear gloves to prevent being bitten by a hidden spider. Also, clothingespecially if unused for a considerable timeshould be checked before wearing, as a spider may have taken up residence within it.

Their shiny black body with a prominent red hourglass marking on the underside of the abdomen is an image that readily comes to mind. DISTRIBUTION In Florida, however, there are three other venomous widow spiders (Southern black widow, northern black widow, and, the red widow) in addition to the brown widow. The most commonly encountered species of the group that people are finding around their homes and work place in Sarasota County is the brown widow spider Latrodectus geometricus . In the mid to late nineties there seems to have been an outbreak of brown widow spiders. Sightings have been reported from the barrier islands to I-75. At one time the brown widow, which was introduced into Florida, was most abundant in coastal cities of southeastern Florida. It now seems to have spread throughout the state and reports of sightings have been received from Georgia, Alabama, Mississippi, and South Carolina. Why are they so common? Perhaps, the milder winters of the last few years have contributed to their expanding range and increased presence. It could be there are more insects for them to feed on as a result of the milder winters. Along with the weather, however, another important factor is transportation by vehicles. The Extension Office has received increasing email and phone calls asking how to control brow widow spiders in and under cars and recreation vehicles.

Talk:Black widow spider From Wikipedia, the free encyclopedia. There are spiders called "brown recluse" spiders, but none called "black recluse" spiders. Somebody must have either been confused or must have picked up some misinformation from the mass media, so I removed the sentence that questioned the relationship between black widows and black recluses. 03:46, 12 Mar 2005 (UTC) The hourglass marking on black widow females is most commonly red but doesn't have to be, nor does it have to be an hourglass shape.

Black Widow Spider Latrodectus mactans The infamous black widow spider is just one of 30,000+ recognized members of the carnivorous spider order that catches insects with webs or jaws. Its venom is 15 times more potent than an equal weight of rattlesnake venom but its 1.7 mm (.07 in.) fangs inject a much smaller amount. Arachnids not only eat but are eaten by many insects. Some gather and store live, paralyzed spiders within their nests for hungry offspring. For this reason, the black widow, like most other spiders, retreats to a far corner of the web when threatened. It then curls up its legs and plays dead. All widows weave their their tangled webs in quiet and protected areas under boards or rocks and in burrows or tree cavities.

The Brown Widow in Southern California In February of 2003, specimens of the non-native brown widow spider, Latrodectus geometricus , were discovered as part of the Los Angeles Spider Survey being conducted by the Los Angeles County Museum of Natural History. This was an interesting discovery and one that is mostly of scientific interest to southern California arachnologists. However, the ensuing media attention that was given to the spider has created the false impression that the brown widow is a new danger in southern California. Reports have correctly stated that the spider's venom is fairly potent but because the spider injects so little, it is not of major consequence. Yet one hyperbolic report stated that the spider hasn't killed anyone so far. This is not surprising because the brown widow is not a dangerous nor deadly spider. Even though it has venom of high toxicity, this is typically determined with injections of venom into mice or rabbits and conclusions from this are inferred with little real-world relevance. Much more relevant is the effects of actual So even though the non-native brown widow is virtually harmless, it is getting all this publicity and people are concerned about it. The hyperbolic response of the media and the general public to this new resident of southern California is ludicrous considering there are millions (maybe billions) of native black widows

Jones, Ph.D. Assistant Professor of Entomology Female black widow spider with egg sac. Class: Arachnida Order: Araneae Family: Theridiidae Common Name Scientific Name black widow spider Latrodectus mactans Species in the genus Latrodectus are commonly known as widow spiders. A number of different species of widow spiders occur in the United States. The black widow spider ( L. mactans ) and the northern black widow spider ( L. variolus ) occur in Ohio, although both are relatively uncommon, especially in the northern half of the state. Other species of widow spiders occasionally arrive in shipments of household goods. The black widow spider has a potent neurotoxic venom and is considered the most venomous spider in North America. However, the female injects such a small dose of venom that it rarely causes death. Reports indicate human mortality at well less than 1% from black widow spider bites. Identification The adult female black widow spider has a shiny, jet black, spherical abdomen with two connected red triangles on the underside that form a characteristic hourglass marking. Note, however, that the hourglass color may range from yellowish to various shades of orange or red. Adult females are about 1/2-inch long, not including the legs (about 1-1/2 inches when legs are spread). Adult males are harmless, about half the female’s size, with smaller bodies and longer legs. The male’s abdomen usually has red spots along the upper midline and white lines or bars radiating out to the sides. Newly hatched spiderlings are predominately white or yellowish-white, gradually acquiring more black and varying amounts of red and white with each molt. Juveniles of both sexes resemble the male and are harmless.

The web she constructs is an irregular, tangled, cris Egg sacs are pear shaped (or oval), brown, papery and about ½ inch long. They hold from 25 to 900 or more eggs, which have an incubation period of 20 days. The spiderlings disperse shortly after emerging, tearing an opening in the egg sac and stay near the sac. After several hours, these second instar spiderlings balloon to the ground and scatter. Growth requires two to three months, with older females dying in autumn after egg laying. Of all spiders, the Black Widow is the most feared. The female’s venom is especially poisonous to people. Despite its reputation, this spider often attempts to escape rather than bite, unless it is guarding an egg mass or if it is cornered and pressed. The male black widow will not bite you. After mating, the female sometimes eats the male (remember, she only has to mate once in her life), earning the name "widow." During the period shortly following mating and laying of eggs, the female black widow can be a little cranky and hungry. After this period (if he lives through it!) the male lives quite comfortably, eating prey captured by the female. The development of his venom sacs stop and become inactive as the male matures, thus making him less of a potential problem than his female counterpart.
