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.

Researchers have discovered a male spider in the Judean foothills of Israel with an evolutionarily effective yet sadistic sexual perversion. For most spiders, the mating ritual involves the male ejecting sperm into the female's vulva, where it is stored it in a pouch called the spermatheca. These receptacles give the female control of when her eggs will be fertilized, by moving sperm onto them before she lays. The spermatheca is a "last in, first out" structure which means that the last male...

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.

Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
