Skywisp Moth

You can easily get those by using a [npc=73531] and let it drop you off on a high mountain at 73,34. There are at least two more positions later on the route, this one ist just the first you will reach. So if there are no spawns at that point left or you want to farm a rare one, just let yourself get carried further.

To use [npc=73531]: You will see those white birds flying around over the entrance of the arena with the four celestials. At this point you can reach them with ranged attacks: Just hit them once and they will pick you up - dont hit them again for now. The albatross will carry you around the isle: If you want to be dropped, just attack them (they will stop flying at this moment, so you can get dropped pretty precise) and kill them.

The northern part is very steep: I had one spawn there that I could not fight (pet battle area obscured) and once I was there I could not get to the highest part again - so be careful not to land there. Also from that point I could only barely reach another albatross: Just from the highest reachable position while jumping and casting a 40y spell I was able to be picked up again.

Much easier to obtain if you fly from Time Lost Waters fatigue area, then slow fall down or use a glider after you are auto-dismounted for zoning into Timeless Isle. Got mine after 1.5 laps around the island, ~40 kills.

This battle pet is found in some hard to reach places on the Timeless Isle. However if you don't want to figure out how to get up there to farm a rare and just want one for your collection, it can also show up as a secondary pet to the wild Rat running around the cart near the npc [npc=73632].
