despawn. I was in pofear to check golems. I saw one up. I commented on it in guild chat thinking someone might want it. and 30 seconds later it was gone. I have no idea when Terror had been killed, so I dont know how long it stayed up. but it definitely depopped while i was there.
edit
I got Dread, and left the broodling up for 65 mins before it despawned. The corpse of course will only last 8 minutes though being such a low level mob

edit : for terror and the broodling stayed up 71 mins 47 seconds. I timed it precisely. then got dread gaain and his broodling lasted 61 minutes 21 seconds. so there is some leeway in the amount of time a broodling can stay up. call it 60 - 72 minutes.

Edit - got terror on 6/22 at 11:54:37. Broodling popped immediately of course and stayed up until 13:23 when I camped cause fright popped and I had to log on an alt to loot. what a surprise to see it still up when I returned. and it lasted a very long time. messing up my ideas on the despawn timer. finally depopped at 13:50:30. so it stayed up a total of 1 hour and 55 minutes and 53 seconds.

Edit - Blowing away all my previous thoughts, I killed Dread at 3:01:24 and expected the other golems within a few hours. so I kept checking back. and broodling is still up at 6:46:55 after Fright and Terror killed and I chose to leave. 3 hours 45 minutes at least it can stay up.

Edit again - killed Fright 4/8 /15 at 6:20:58 AM. went to work, 1/2 day. came back and iksar broodling still up at 12:28. so I figured it has to depop soon. so I stayed and sure enough - depop at 12:35:42. a total time up of 6 hours 14 minutes and 44 seconds.
