Scientific classification: Black widow spiders make up the genus Latrodectus in the family Theridiidae. The name is applied especially to the familiar North American species Latrodectus mactans.

Extractions: (Araneae: Theridiidae) Facts: Black widow spiders are shy and secretive and found in seldom-disturbed areas. 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.

Black Widow Spider Latrodectus mactans (Fabricius), Theridiidae, ARANEAE. DESCRIPTION. black widow spiders can also be killed with pesticidal sprays.
http://ipm.ncsu.edu/AG369/notes/black_widow_spider.html

Extractions: Latrodectus mactans (Fabricius), Theridiidae, ARANEAE Adult Like all spiders, the black widow has 8 legs; however, males and females differ in appearance. Females are about 40 mm long with legs outstretched and have black, globular abdomens about 9 by 13 mm marked with a red or yellow hourglass shape underneath. Males are lighter in color and have a red or pale brown stripe down the middle of their backs from which white or yellow streaks radiate. Males are smaller (up to 30 mm long with legs outstretched). The male pedipalps (biting appendages at front of head) are noticeably swollen. Egg Eggs are incorporated into grayish, silken balls about 12 to 15 mm in diameter. These egg masses contain 200 to 900 eggs and are found in the spider's web. Nymph Entirely white at first, nymphs develop through five to eight instars. As they develop, nymphs become more similar in appearance to adult males, though smaller. Distribution Though more abundant in the southern states, the black widow spider occurs throughout most of the Western Hemisphere. This species may hide in sheltered, dimly lit places such as barns, garages, basements, outdoor toilets, hollow stumps, rodent holes, trash, brush, and dense vegetation. Black widows usually seek dry, sheltered sites such as buildings during periods of cold weather. Feeding Habits This spider feeds primarily on insects and other arthropods but, when disturbed, it may bite people or animals.

Extractions: Status: IN STOCK ANR-1039, New Aug 1997. Faith M. Oi, Extension Entomologist, Assistant Professor, and Thomas G. Shelton, Graduate Research Assistant, both in Entomology at Auburn University The Black Widow People are often afraid of spiders because of their ill-deserved reputation for envenomizing victims. In fact, most spiders do not have mouthparts strong enough to penetrate skin. Spiders are considered beneficial arthropods because they often prey on insects that we consider nuisances. Therefore, homeowners should be encouraged to leave spiders alone if the spiders are in their natural habitat such as the garden or yard. However, the black widow spider (Latrodactus mactans) is an exception. Description The black widow female is most easily recognized by its shiny black body and red hour-glass marking on the underside of its abdomen (Figure 1). The red marking can also be two separate spots of red. Females range in size from 5.0 to 13.5 mm (0.20 to 0.50 inches). Males range in size from 3.0 to 5.0 mm (0.12 to 0.20 inches), are completely black, and are seldom seen.

Asthma You are in: Bites and Stings Black Widow Spider Bite Overview Spiders are often blamed for all kinds of symptoms, from local itching to diffuse rashes. The fact is that spiders rarely bite humans, and in fact, most spider bites do not even break the skin with their bites. The bites of very large spiders such as tarantulas can be painful. Otherwise, in the temperate regions, the only spiders to be feared are the black widow and the brown recluse. The black widow is a medium-sized spider whose body is about a half-inch long. The name is derived from the mistaken belief that the female invariably kills the male after mating. Two species are common to the United States.

Hesperus: Oklahoma, Kansas, and middle Texas throughout the southwestern states; L. geometricus: world wide in the tropical zone. DAMAGE BIOLOGY EGGS The eggs sacs can be constructed by the females in one to three hours and are approximately 1 cm in diameter. Each female can produce 10 to 20 of these sacs during a lifetime, and each sac may contain 200 to 250 eggs. The eggs hatch within the sac in about two weeks. ADULTS The spiderlings undergo their first molt three to four days thence. In approximately 10 days they emerge from the sac through one to three holes that are about 1 mm in diameter. The spiderlings remain in the nest area for several weeks (135-240 days) where they undergo six to nine molts before reaching maturity. Female black widows can live 850 to 950 days when food is readily available. BEHAVIOR The brown widow spider is the most abundant and is commonly found in urban areas. It may be found indoors; however, favorite outdoor hiding places include the crawl space beneath homes and amongst piles of stored lumber, hollow tile blocks, abandoned vehicles, storage sheds, and stored items on shelves. Within the home, the brown widow may be found beneath tables and desks, behind shutters, in the angles of doors and windows, in the folds of clothing, in shoes, and under objects in dark, little-disturbed areas. The black widow spiders are less common and are generally associated with arid areas (western black widow) and higher elevations (southern black widow). Both can be found in crawl spaces, under rocks, in tiny voids, and in utility ducts.

Extractions: Click here to read more. There are at least 50,000 spider species in the arachnid family. Spiders are defined as having eight jointed legs, no wings, no antennae and only two body sections: the thorax and the abdomen. Spiders spend their entire life span capturing and eating other insects (about 2,000 in a year). Even though spiders do a great deal of good for our environment, spiders are greatly feared by most of the population. Most spiders are killed only because they scare people, not because they are actually dangerous to humans. All spiders have some amount of venom with varying degrees of potency. The fangs of a spider are hollow. The venom is injected through the fangs into the victim (usually an insect). The venom will rapidly paralyze the victim and aid in digestion. Fortunately, most spiders are not dangerous to humans because their fangs are either too short or too fragile to penetrate human skin. Spiders do not attack in herds. Spiders do not lay in wait and attack people. Spiders do not lift the covers at night and crawl into bed to bite people as they are sleeping. Some spiders can jump but they are not intentionally jumping at humans to attack them. A spider generally bites a human because it was scared and bites to defend itself. Spiders generally prefer to live in undisturbed areas such as corners of the house or the eaves or in the garden where they can catch insects in peace.

Extractions: The bite of a black widow is not painful at first, and feels like a pin prick. Within minutes of the attack, though, the pain becomes more and more intense. The pain and swelling spread throughout the body, and are accompanied by nausea, lymph node pain, loss of coordination, sweating, elevated blood pressure and respiratory difficulty. The bite can be fatal, but recovery usually occurs within 2 to 5 days (North Carolina State University: Center for Integrated Pest Management; Stibich, 2002)
