Lagrange clouds and NSPs in general are just containers for spaceborne life, so the question isn't where those can be found, but where life can be found. The thing is, not only is that region-specific, but also often quite arbitrary. If you're searching under the right conditions, you'll soon find what you're looking for.
If.
But that can be very specific.
Here's an example: a friend of mine headed for the Vulcan Gate region (he's a Star Trek fan) soon after launch, hoping to find some new Codex entries there. He surveyed the nebulae, he even found three new planetary nebulae, he searched various areas: all for naught.
Much later on, it turned out what he should have looked at were specific white dwarf stars only, in a rather small area of the region. If he did that, he would have been tripping all over NSPs. Of course, these were specific to that region only.
So, that's what I meant with very specific and arbitary conditions. In practice, how it works is that a Commander might be extremely lucky enough to randomly stumble into one NSP, then it (hopefully!) gets logged into the Codex - oh wait, there are times when it doesn't, because the Codex is still bugged - then either the Commander in question, or later other Commanders, look through the area and find more.
Also, the bubble's region, the Inner Orion Spur, appears to have far more NSPs than the other regions do, even when accounting for the fact that it has the most traffic.
As for the DW2, all the Commanders there, and only one new find was discovered: Aster trees and pods. We'll see if there will be anything new once the expedition is entirely over, but personally, I doubt it.
