omnivorous

Having a diet which is neither exclusively carnivorous nor exclusively herbivorous.

Having an interest in a variety of subjects.

The Beckettian progression appears occasionally: while Miss Counihan (static) is an omnivorous reader and Murphy (transitional) a strict non-reader, Cooper is an analphabete.

He was omnivorous in his appetite for knowledge, quite catholic in his range of interests […]

All-consuming.

Of a parasite: attacking many species; not confined to a single host plant.
