The Bite of a Brown Widow Is Venomous

The female brown widow is a venomous spider that injects a neurotoxic venom when it bites its prey. The males do not bite. Experts disagree on the potency of the brown widow spider's venom, with some saying it is more potent than a black widow's and some offering the opposite point of view. The consensus is however, that it is more timid and injects less venom than the black widow spider.

Bites occur usually through accidental contact and pressing of the spider against the skin. Symptoms of a brown widow spider bite include a red mark at the bite site and some pain locally. The bite is not usually life threatening, and is considered less serious than a black widow spider bite.

Differences between Black Widows and Brown Widows:

  • The color of the brown widow spider is tan to brown or gray vs. black.
  • The egg sac of a brown widow has tiny spikes all over the surface; a black widow's egg sac is smooth.
  • Brown widows produce more eggs and offspring than black widows.
  • A brown widow's bite is usually less severe than a black widow bite as they tend to inject less venom.

The Saguaro Video
The Saguaro often begins life in the shelter of a "nurse" tree or shrub which can provide a shaded, moister habitat for the germination of life. The Saguaro grows very slowly -- perhaps an inch a year -- but to a great height, 15 to 50 feet.

The Desert Food ChainDesert Food Chain Video
A food chain constitutes a complex network of organisms, from plants to animals, through which energy, derived from the sun, flows in the form of organic matter and dissipates in the form of waste heat.
