Florida Black Widow Spider


Member of the genus Latrodectus, the most recognizable of the Florida spiders is the black widow, Latrodectus mactans. The Florida black widow spider is indigenous to the state. Because of this, it is the most widespread spider in Florida. The female Florida black widow spider is especially dangerous to humans because of her enlarged venom gland. Widow spiders are also known for their bizarre mating habits, at times resulting in the female killing the male after fertilization.

Appearance of Florida Black Widow Spiders
The body of an average adult male Florida black widow spider is a fourth of an inch long and between a gray and black color. The female is a much larger one and one half inch long and shiny black. The bright red hourglass shape on their stomachs is how most typically identify Florida black widow spiders.

Development of Florida Black Widow Spiders
The adult female Florida black widow spider produces four to nine egg sacs in a summer, each sac containing between 100 to 400 eggs. Twenty to thirty days later spiderlings hatch form the eggs. It takes the spiderling another six to nine months to become an adult, but Florida black widow spiders can begin to reproduce just two to four months after hatching.

Behavior of Florida Black Widow Spiders
The Florida black widow spider primarily seeks to nest in relatively secluded places where they can be protected. Outside in piles of wood, under rocks and around corners of buildings are common places for the Florida black widow spider to spin its web. Although not characteristically aggressive, it will bite humans if accidentally squeezed or to protect its egg sacs.
