This morning at 7AM EST, on 2016-08-31, I was able to locate at least 5 of these.  Enough to battle 3 to get an uncommon.  Also I was able to battle several Arcane Eyes.  I was on ly 87 Mage.  I hope this helps others.

This morning (2016-08-21) I was able to find a ton of these around Kharazan.  It was around 7AN EST.  There were also several restless shadelings under ground.  I was on my level 87 mage.  I hope this helps others.
