| | Mating (from spider) -- Britannica Student Encyclopedia |
| | In most groups, after a male has successfully approached a female and mounted her, he inserts his left pedipalp into the left opening of her genital structure and the right pedipalp into the right opening. | | | In some primitive spiders (e.g., haplogynes, mygalomorphs) and a few others, the male inserts both pedipalps simultaneously into the female's genital slit. | | | Natural history > Reproduction and life cycle > Mating |

| | Science News: Male spiders amputate organs, run faster |
| | Irschick rates the spiders as an "extreme example" of a species that "got stuck in a massive evolutionary conflict and had to evolve a behavior to get out." As males shrank and females enlarged during the course of T. sisyphoides' evolution, the species probably couldn't afford to reduce pedipalp size too much, says Irschick. | | | The male spider grows to only about one-hundredth the size of a female, yet one pedipalp accounts for some 10 percent of his body mass. | | | Although these spiders haven't been studied in depth, researchers had noticed that within hours after a young male's penultimate molt prior to mating, he amputates one of his pedipalps. |

| | The male does this by inserting the mating organ at the end of its pedipalp (a spine-like structure on tip) carrying the sperm, into the female's reproductive (epigynal) opening on the underside of her body. | | | Different spiders mate in different positions, but in all cases the aim is to transfer sperm from the male to the female. | | | In some species the tip of the pedipalp will break off during mating or a hardened secretion will block the females openings, preventing other males from mating with that female. |

| | Whether his partner is a defenseless, molting juvenile or a consenting though potentially aggressive adult, the male goes into his death throes within moments of inserting the second of his two pedipalps (mating appendages) inside the second of the female's two genital apertures. | | | Within fifteen minutes--and usually sooner--his heart stops, even when the female is prevented (by experimenters) from molesting him. | | | A further bit of proof that death occurs without female complicity: one male, after inserting his first pedipalp in the normal place, moved elsewhere on the female's web and inexplicably inserted his second pedipalp into a nearby dead mealworm. |
