Red Widow Spider

Latrodectus bishopi is the scientific name for the red widow spider, which is endemic to certain habitats of central and southern Florida, where it lives primarily in sand dunes dominated by sand pine, Pinus clausa – a type of vegetation found only in peninsular Florida.
== Description ==
The red widow, L. bishopi, has a red-orange cephalothorax, its abdomen is black with yellow rings outlining the rows of red spots and its legs are vermillion red. On its underside, it does not have the familiar hourglass marking, but a small red bar. Females are almost double the size of the male.
L. bishopi is believed to be venomous like the other Latrodectus members, though no bites by this spider are recorded in the medical literature; unlike cosmopolitan species such as the black and brown widows, it seldom comes into contact with humans. The median lethal dose (LD) of the spider's venom has been measured in mice as 2.20 mg/kg (with a confidence interval of 1.29-3.74), and each spider contains about 0.157 mg.
