Swarm: What do you do against it?

[Taqwus]

Storms would work, as would a damage shield (Charcoal Shield for non-mages, Fire Shield for fire mages say) or possibly a damaging aura (e.g. cold from the one cold-radiating armor, or the life draining from bone armor, etc).
Storms will also help prevent the Swarm + Haunted Forest abuse, or at least make it less likely that you're suddenly surrounded by fatigue-causing undead plant beings.

You might also try the point blank damage spells (Burning Hands etc.) - make sure the caster and any friendlies near him are resistant. Abysian Salamanders hit the whole square, as do Fire/Ice Drakes and the Harvest Blade (not necessarily the most practical solution, but effective). Some other attack spells, mostly Fire, hit the whole square. Fire elementals and Fire Shield could fry all the dragonflies.

If they do all turn into manikins after you kill them once - then you'll have to kill them again. All of the above will work (except maybe the ice drake - are manikins cold immune like real undead?), plus I think manikins can be Banished.

Nope. Manikins are not cold immune and can be frozen to death by Breath of Winter, Murdering Winter, etc.

Swarm is a good distraction (nothing like having your mages drop niefel flames on a bunch of dragonflies - right next to your front line) but gets really nasty when combined with spells like 'Life After Death'. "Wtf!? Where did all these soulless come from?"
