Hey I appreciate the notes. I have a group of 6 I am running through Whispering Cairn, but am setting Age of Worms in Eberron.
I modeled the acid beetle swarms after Zairital Swarms. Three were pretty tough on the group and most of the party was down at one time.
I am trying to post my conversion notes on my website, but since I seem to be a bit behind the others here, it may not help y'all.
My conversion notes are at: http://www.geo-verse.com/A4E-Notes/A4E-Conv-4.html
They might get to the face in the hall next session, but they should find the last latern before that.
Whether they will light them is another matter.
