June 21 is the first official day of summer, and that means the Qiraji Guardling
has begun spawning on all servers. Like its counterpart the Snowy Owl, this pet is only seasonally available, which means you've got a limited time to capture one for yourself. The Guardling spawns in southern Silithus, along the walls of Ahn'Qiraj -- both inside the entrance area, and just outside near the Scarab Wall. The pet spawns anywhere from poor to rare quality, and is always accompanied by two other critters, so make sure you've got a decent team put together before you set out.
The Qiraji Guardling is on the list of required pets for the World Safari
achievement and its associated Zookeeper
title, so if you're looking to complete those achievements, you'll want to grab one of these pets while they are available. No need to hurry too quickly, though -- the Qiraji Guardling will keep spawning until the Autumnal Equinox, which falls on Tuesday, September 23 this year. Happy hunting!
