The Brown Widow Spider is a cool spider that belongs to the cobweb spiders family. Some people know more about its cousin, the Black Widow, but the Brown Widow has its own interesting story. People once thought it came just from South Africa, but now we know it lives in South America and other parts of Africa too.
Female spiders lay 12-150 eggs in a thorny or spiky tan-colored sac. Throughout their lifetime, they can produce around 20 sacs maximum. It takes around 20 days for the hatchlings to come out of the eggs.
Upon birth, survival becomes a brutal game, as spiderlings display cannibalistic tendencies. As they grow, they undergo a process of shedding old skin and developing new layers.
Built from silk threads released from their spinnerets, the Brown Widow Spider’s web lacks a consistent pattern. Notably, they often design a retreat area within their web, allowing the female spider to hide when sensing potential danger.
Yes, Brown Widow Spiders have venom. They use it to help them catch the bugs they like to eat. Their venom is strong, but not as much as their cousin, the Black Widow.
Yes, Brown Widow Spiders can bite. They usually keep to themselves, but they might bite if they feel really scared or trapped.
The Brown Widow Spider helps control insect populations, aiding in ecosystem balance and protecting crops from overpopulation.
Natural Predator: The Brown Widow Spider’s existence isn’t without challenges. Predators like digger wasps and mud daubers see them as an essential component of their diet.
Prey-Predator Dynamics: While these spiders face a consistent threat from their natural predators, their numbers haven’t dwindled. This could be attributed to their prolific breeding habits or their adaptability in diverse habitats.
Relationship with Humans: The Brown Widow Spider generally exhibits shy behavior, tending to keep away from human interaction. They are more likely to flee than engage when encountered. Bites, although rare, generally happen when they feel cornered or threatened. Affected individuals might experience redness, pain, and in severe cases, symptoms caused by its neurotoxic venom like vomiting or muscle rigidity.
