Perhaps it is not a thought that crosses the minds of the average male, but spiders have more to consider than most other creatures when it comes to choosing a mate. Biologists have long known that some male spiders sacrifice their genitals in the act of reproduction and that doing so leaves them sterile, but no one could adequately explain why this was so. An answer, however, may now be at hand following a series of meticulous experiments by Daiqin Li, a behavioral ecologist at the...

These receptacles give the female control of when her eggs will be fertilized, by moving sperm onto them before she lays.

The Daddy-long-legs Spider (Pholcus phalangioides), also known as the Cellar Spider or Skull Spider, is a species of arachnid found in many parts of the world, but originally came from the tropics. They are commonly found living in caves, garages, ceilings of household rooms, and cellars. In Australia, it is considered a beneficial species as it kills and eats the venomous redback Spider. There is some confusion with the common name "daddy longlegs". This name is also applied to two other...
