Comb-footed or tangle-web spiders are other names for black widow spiders.The fingernail-sized black widow weaves irregular webs and captures victims with its combed hind set of limbs, earning both names. The black widow spider is a black-colored spider with a gleaming surface and is shiny black.It has a red hourglass shape or orange hourglass shape on it. The colorful, red hourglass-shaped mark on the abdomens of black widow spiders is well-known. Female black widow has a length of 1.5 in (3.81 cm) measure includes their limb span. On rare occasions, the hourglass marking will be orange-yellow.Females are said to feed on male spiders after mating, which is how the spiders got their title. Mate cannibalism is the term for this type of behavior. It’s primarily been seen in laboratory cages where males can’t get out as the females want to eat them. In the wild, on a few occasions, males may quickly flee. Mating happens around the spring season. When males go out in search of receptive females, courtship begins. Males can inseminate females who are interested in mating by remaining still. Female black widows in grape-growing regions are petite and round. They look like shiny black or red grapes. A tiny sac holds the eggs of the black widow spider. Each sac, which has a diameter of about 0.39 in (1 cm) and can contain 200 to 250 eggs, will hatch in about two weeks. The eggs hatch inside the sac, and the “spiderlings” stay there until they molt for the first time. Female black widows can have up to twenty sacs in their lifespan and are fiercely protective of them. They will bite in defense of their children when tending to their egg sacs.Male black widows are brown or grey, with tiny red patches. Male black widows are significantly smaller than female black widows. The male black widow’s legs are brown and considerably longer than the female’s and are characterized by orange and brown colors at the joint. Some have two red spots on their backs, and others have no markings.Mosquitoes, flies, grasshoppers, and beetles are the principal prey of the black widow spider. The spider hangs upside down in the web’s center. The spider moves forward and injects the poison into the insect before wrapping it in silk before it can escape the web. The black widow spider pumps a digestive liquid over the fly, which dissolves and allows capillary action.Black widows do not hunt humans. They like to eat other insects, and their young have been observed devouring one another for nutrition. Only the most resilient individuals can escape the black widow’s web and nest. When humans dash into the webs or try to handle the spider, they are usually bitten. Bite reactions are more likely to be bad in children, the elderly, and people with health problems. The bites are not deadly for most of us, but they can be agonizing. They produce an unusually strong toxin, resulting in a disease known as latrodectism. Female spiders have huge poison glands, and if they bite humans, it is dangerous. Their poison is greater than that of a rattlesnake.On the other hand, the spiders rarely bite, and bites are seldom lethal. They only bite humans when they are startled. A fever, increased blood pressure, sweating, and nausea are all symptoms of bites. These symptoms can last anywhere from three to seven days, but they rarely stay more than a week. Within minutes, pain begins and quickly spreads to various parts of the body. When the spider wraps the prey, this is used to drape the silk over it. Females have a body length of 0.51 in (1.3 cm).If you enjoyed this article, why not also read about the world’s biggest spider and Florida spiders or here on Kidadl?Where are black widow spiders found?Black widows can be found in mild climates all around the world.
