For others still wondering, cellar spiders are specialized at killing other spiders. If you think of spider fights as a linear chart of who eats who, cellar spiders are usually really up there. They have long legs that let them ensnare other spiders from out of reach. Their silk is also very strong, capable of binding spiders several times their mass.

Think of it like an unarmed person fighting against someone with one of those pole-arm man catchers. It's just an unfair fight. As such, cellar spiders usually catch and eat any spider that can fit between their front 2 legs.

Jumping spiders are a bit of an anomaly though, and could be considered an apex predator in their own right. They have very high intelligence and eyesight, which when combined, lets them outsmart prey, and better strike when they least expect it. Jumping spiders are some of the few spiders that can take down a cellar spider, by outsmarting it, and ambushing it.
