What are daddy longlegs spiders or aphidsuckers?

There are there grand(daddy) long legs. A phoilcidae (cellar spider), a tipulidae (crane fly), and opiliones. The crane fly eats nectsr. The other two eats small insects. I have been told the opiliones are aphid eaters. The things I found just makes it seem like they would it it was there. Not an aphid only diet though.
