Have you tried wiki'ing them?
Regardless, they're a parasitic lifeform led by the Gravemind, which burrow into a host and turn it's body into a walking corpse. Their intelligence depends on whether a Gravemind is currently active or not.
Well the things the Nids nom turn into biomass for the Nids to make more Nids. And considering their largest Hive Fleets is bigger then a galactic arm, it seems like they don't need it, but hey I ain't the galaxy eating hored of bugs. :\
In any case, if we do ever have the Flood go against the 'Nids they may go against Hive Fleet Nidhoggr.
The Flood would integrate the knowledge of their adaptive abilities into themselves after the first infection, meaning that they would be able to constantly adapt to counter the Nids's adaption.
