Spiders can have a mutually benifical relationship with pitchers. Pitchers draw in the flys and the spider will catch them but the efficient spiders will catch even more flys than the pitchers would catch on their own. The spiders suck the bugs dry and drop the carcass into the pitcher later adding thier own droppings to the pitcher. With likely a higher catch rate and less escapees there’s no loss to the pitcher.
