Spider: Red Back VS Black Widow

Extra information:

"The notorious Black Widow Spider (Latrodectus sp) of the United States is a close relative of the Redback Spider (Latrodectus hasselti), and only differs in appearance by the absence of a red dorsal stripe." [Link]

"The black widow spider (Latrodectus spp.) is a spider notorious for its neurotoxic venom."

" The redback spider has a neurotoxic venom which is toxic to humans with bites causing severe pain"


"Although the name 'black widow spider' is most commonly used to refer to the three North American species best known for their dark coloration, black hair and red hourglass pattern, occasionally it is applied to several other members of a the Latrodectus (widow spider) genus in which there are 31 recognized species including the Australian red-back, brown widow spider (sometimes called the gray widow), and the red widow spider."
