Larva

Larvae are employed as the young stage of various insectoid creatures, notably the silithids and nerubians.

Achievements
Killing one of these is required for.

Note
Don't be discouraged by the abundance of Maggots in the Dead Scar - Larva definitely spawn in the Ghostlands! However there seems to be not a specific area where they can be found. Probably the fastest method for Larva spotting is riding around the zone while hitting a key that is bound to a targetting macro ("/tar Larva").
