Alan McStravick for redOrbit.com - Your Universe Online The idea that the female of a species would, after completing coitus, approach, kill and eat her mate is a sentiment that instills, if not fear, unease in many the male reader. This scenario, in fact, is exactly how the Black Widow spider got its name.

Male praying mantises are more likely to engage in risky mating behavior if they have not had recent access to females, as reported Apr. 25 in the open access journal PLoS ONE. Female praying mantises are known for their cannibalistic behavior toward their mates, and males take a large risk when they attempt to reproduce. In the current work, led by William Brown of State University of New York at Fredonia, the researchers found that males modulate this risk by altering their approach rate...

Discerning males remain faithful...if you are a spider. Sex for male orb web spiders (Argiope bruennichi) is a two shot affair since the act of mating destroys their genitalia. If they survive being eaten during their first encounter with a female, they have two choices — to mate again with the same female (monogynous) or try to find a new partner (bigynous). New research published in BioMed Central's open access journal Frontiers in Zoology shows that choice of mating behavior for A....

The work was the first "natural" study to validate the legend about spiders exhibiting such behavior, and shows why it may be...

Female spiders are voracious predators and consume a wide range of prey, which sometimes includes their mates. A number of hypotheses have been proposed for why females eat males before or after mating. Researchers Shawn Wilder and Ann Rypstra from Miami University in Ohio found, in a study published in the September issue of the American Naturalist, that the answer may be simpler than previously thought. Males are more likely to be eaten if they are much smaller than females, which likely...

There are two closely related species to the Southern Black Widow; the Western Black Widow (Latrodectus hesperus), and the Northern Black Widow (Latrodectus variolus). These three species are often confused with the genus Steatoda (false black widows). The black widow was first described in 1775 by Johan Christian Fabricius. The...
