After the evening server restarts on 3/11, I logged on immediately once my servers were back up, and finally saw one without being on a FP. I darted at it, and only noticed at the last second that two other players landed at the same time. I pressed my Scourged Whelpling macro, which targeted it, but I was too late. Rinse. Repeat. I logged in the next night, a few hours after reset time, and spotted two of them up. An uncommon and a poor. Left the poor for someone else to find.

When I got to the Dry Hills on my 33, there were lots of 90s flying around the area. I got lucky and found one just south of the Dry Hills area (poor, but still). It was sitting amongst an Adder and a Prairie Dog, so I almost missed it. Make sure to include that area, near the prowlers, and you could get lucky, too.

As others have stated, they spawn with no backup over by the small side tower of Karazhan, and over by Lydia Accoste. When I went there to fight her, there were several around the other side of the tower. Got rare on my second capture. :)

While running a figure 8 through Sable Ridge many, many, many times, I have an Uncommon Twilight Beetle and rare of everything else in the area. There just aren't enough of these there.
