The beekeeper from the hunter exam was revisited when she and her love are ambushed and killed by Chimera Ants.
Her ability to control bees (insects) likely would have fostered an ability in life, but in reincarnation into an ant, she's certain to have some heirarchical control or mind control ability.
Likely there is a nen ability capable Ponzu-like ant creature wherever Pariston is keeping them (possibly the same space as the missing hunters). I suspect we will come back to them once Pariston's full plans are revealed (I'll be honest, I doubt he has a plan beyond mayhem)
