The female black widow spider is larger than the male, and therefore carries more venom.
I would say the female because it has more venom than a male black widow
U know female r more selfish than male. After makeing sex female spider thought that she is now powerful for live. No need male spidr. When female spider pregnant they could not go out for food. then they eat male spiders.
Yes, especially when the female has young cubs to protect.
'cause females bite, but males don't.

The male Sydney Funnel Web spider is more dangerous to humans than the female. Their venom is stronger, and they wander in search of females, which makes them more likely to come in contact with humans. Female Sydney Funnel Web spiders remain in their burrows for most of their lives.
Yes. Spiders have eight legs and two more, shorter, limbs at the very fronts of their bodies that are called "pedipalps." They are used the way we use our arms. However, male spiders use their pedipalps to impregnate their mates. The male pedipalp functions like a biological syringe. The male makes a little doily-like web on the ground, discharges semen onto that felt-like silken fabric, and then inserts the tips of its pedipalps into the drop of semen. The semen is sucked into the pedipalps, and later on the male spider inserts each pedipalp into the genital opening of the female spider and the semen is forced out of his pedipalps and into her reproductive system. Therefore, the pedipalps of male spiders are very different from those of female spiders. Male pedipalps have to be much bigger than those of female spiders. So if you see a spider with two pedipalps that are terminated by big roundish things, then that spider will be a male. In many species of spider the males are very much smaller than the females. All they have to do is to deliver a couple of small droplets of semen to the female. They don't have to produce hundreds of eggs, guard the eggs, guard the babies for a while after they have hatched, etc. So there is no particular biological reason for male spiders to be big. In fact, if they are small enough it may be very difficult for the female to catch them before or after intercourse, and since they are so small it may not even be worth the effort to catch them to eat them. So maybe that is the reason that in lots of spider species the males are much smaller than the females. In many spiders that have good vision because they are hunting spiders (e.g., lynx spiders, fishing spiders, wolf spiders, and jumping spiders), the males may look different from the females. Looking special helps ensure that the female will realize that this other spider is a male and not a female coming to try to kill her, and that this spider is a male of the female's own species. The male's special appearance is also involved in the elaborate dance that many species of hunting spiders use to identify themselves by species and then to "entrance" the female spider so that she will put aside thoughts of eating him and let him mate with her.
In the animal kingdom, females could get agresive protecting the offspring.
I think they would be wasps,dangerous spiders, and lots more.
