As of the September 2010 update, monster AI behavior has been altered. Single monsters are pullable without a sac-pull, however monsters do link. A sac pull *may* to no longer be necessary. (Tested pulling single small monsters, and it works. Small groups can farm small monsters for coins as a result) this is true and in addition a random number and assortment of remaining antlions (boss included) will randomly run to where the previous antlion was defeated and then they will immediately turn and go away. this is unlike the crabs which will come to the corpse and stay there.
Albino Antlion (normal model) use Sandpit and Sandblast (blind and silence), casts Break and Stone III.
Anthracite Antlion (black model) casts Stonega II.
Only the three Myrmeleontide need to be defeated in order to win. Doing so will instantly kill all other monsters.
