The Biology of the Black Widow
The Black Widow, also known as Latrodectus mactans, is a member of the Theridiidae family of spiders. There are over 30 species of Black Widows found throughout the world, with the most common species being Latrodectus mactans, Latrodectus hesperus, and Latrodectus geometricus. Black Widows are relatively small spiders, with a body length of approximately 1⁄4 inch (6-8 mm) and a leg span of up to 1 inch (2.5 cm). They are recognized by their sleek black body and distinctive red hourglass shape, which serves as a warning to potential predators.
The Venom of the Black Widow
The Black Widow’s venom is a powerful neurotoxin that can cause severe pain, muscle cramps, and breathing difficulties. The venom is produced in the spider’s salivary glands and is delivered through the spider’s fangs, which are capable of penetrating human skin. The venom is a complex mixture of compounds, including latrotoxins, which are responsible for the spider’s toxic effects. While the venom is highly toxic, it is relatively rare for a Black Widow bite to be fatal, with most reported deaths occurring in children, the elderly, and people with pre-existing medical conditions.
| Species | Venom Toxicity | Body Length |
|---|---|---|
| Latrodectus mactans | 15 times more toxic than a rattlesnake | 1/4 inch (6-8 mm) |
| Latrodectus hesperus | 10 times more toxic than a rattlesnake | 1/4 inch (6-8 mm) |
| Latrodectus geometricus | 5 times more toxic than a rattlesnake | 1/4 inch (6-8 mm) |
