Stingtail Nest
The Stingtail Nest vignette is found at [59.0, 45.2] just east of the Murkbog in central Spires of Arak. A big swarm of Stingtail Drones and Stingtail Wasps are guarding the nest. Kill any one of them to summon rare wasp Sunderthorn, queen of the Stingtail:
- Sunderthorn descends from the treepots to protect her hive!
Defeat Sunderthorn and loot the corpse for 
[Stingtail's Toxic Stinger] and 20-30 
[Garrison Resources].
Immediately to the west, near a Logging-capable tree, is Mysterious Flower, Spires of Arak version.
Tracking quest
To check whether Sunderthorn has been looted, copy and paste this command into the chat window:
/run print(C_QuestLog.IsQuestFlaggedCompleted(36298))
If a "true" appears in the chat window, Sunderthorn has been looted; "false" indicates the opposite.
