This quest is part of the Rise of the Silithid quest chain.
All right now, these reports about the bugs... what we know is that they are draining the water pools that used to be where the Noxious Lair is. What we DON'T know is, well, everything else.
Let's figure out who our enemy is first! I want you to head into the Noxious Lair and get some parts off of those critters. Get five from the Centipaar there and bring them to Alchemist Pestlezugg for him to dink with. With him on the case, we'll figure out what they are!
You're Junior Surveyor <name>, yes? Quickly now, there is a dire situation at hand! Do you have the insect parts that Fizzledowser said you would?!
Good work - I'll start my analysis on these now! I can tell you right from the start though... these are nothing like any insect form I have ever seen. It's almost as if these bugs are being controlled by an outside force or something.
You need to go talk to Fizzledowser right away; apparently there is an emergency that he needs your help with on the double! I'm not sure, but I think it involves more of the bugs in the Tanaris desert!
Upon completion of this quest you will gain:
Simple as can be: Critters whose name include 'Centipaar' drop the parts. Drop rate is about 40%
