You've sold me on CR 5. I do think the centipede swarm poison is a boost for them, though.
Great Fort is ok by me.
Your proposed org line is fine.
Updating the Whizz-Bang Beetle Working Draft.
I changed the addition to whiz-bang to "after damaging a target the swarm can continue moving through or around the target's space" since I think it reads better.
Tactics thoughts?
Hmm…
These beetles attack anything they detect with their combustion sense, which includes any creature carrying a torch or other heat source. They rely on their whiz-bang attack in combat, but occasionally use normal swarm attacks against slow or stationary targets. Any intruder unfortunate enough to be between a whiz-bang beetle swarm and a fire source is likely to be harmed as the beetles fly past them to attack the flames.
