This is what a black widow bite looks like
There are three main species of black widow spider, all of which have very similar characteristics and inhabit areas in Northern America and parts of Mexico. Until very recently all three species of black widow spider were classified as one but recent research shows that as the species inhabit different areas, the three species of black widow spider have adapted to their environment in different ways.
The Northern black widow spider is primarily found in the north east of the USA and parts of south east Canada, although the range of the northern black widow spider overlaps with that of the western black widow spider a great deal.

The Western black widow spider inhabits areas of the western USA, Canada and parts of Mexico, although these western black widow spiders are often confused for the False black widow spider in Canada.

The Southern black widow spider is found throughout the states in south east America from Florida right up to New York, and are also found more west towards Texas and Arizona where the black widow spider is said to run rampant.

Black widows are notorious spiders identified by the colored, hourglass-shaped mark on their abdomens. Several species answer to the name, and they are found in temperate regions around the world.

This spider's bite is much feared because its venom is reported to be 15 times stronger than a rattlesnake's. In humans, bites produce muscle aches, nausea, and a paralysis of the diaphragm that can make breathing difficult; however, contrary to popular belief, most people who are bitten suffer no serious damage—let alone death. But bites can be fatal—usually to small children, the elderly, or the infirm. Fortunately, fatalities are fairly rare; the spiders are nonaggressive and bite only in self-defense, such as when someone accidentally sits on them.

The animals most at risk from the black widow's bite are insects—and male black widow spiders. Females sometimes kill and eat their counterparts after mating in a macabre behavior that gave the insect its name. Black widows are solitary year-round except during this violent mating ritual.
These spiders spin large webs in which females suspend a cocoon with hundreds of eggs. Spiderlings disperse soon after they leave their eggs, but the web remains. Black widow spiders also use their webs to ensnare their prey, which consists of flies, mosquitoes, grasshoppers, beetles, and caterpillars. Black widows are comb-footed spiders, which means they have bristles on their hind legs that they use to cover their prey with silk once it has been trapped.

To feed, black widows puncture their insect prey with their fangs and administer digestive enzymes to the corpses. By using these enzymes, and their gnashing fangs, the spiders liquefy their prey's bodies and suck up the resulting fluid.

The female black widow spins a silken web usually inprotected place such as under stones, house steps, decks, ets The webs are irregularly shaped with stands running in many dirctions. They are said to appear messy. The spider hide during the day, and hang upside down in their webs at night.
Black widows are beneficial predators feeding on roaches, crickets and other pests.
Seldom is the spider found inside houses and black widow spiders do not aggressively hunt humans. when they bite it is to defend themselves or their eggs. The black widow venomis a nerve toxin. The

initial bite may feel like pin prick. Although bites are
generally not fatal, they should be considered dangerous. Contract your local poison control center
immediately. If possible, capture the spider for identification.
