I think probably that it's colonizing, but the ones that have been on earth for thousands of years have gotten curious about/less hostile to the locals - hence the tapering off of giant mythological monsters as things get closer to the modern age - before getting riled up by signals from another group/the main bunch that they would be arriving soon (the s2 super-hive group) and fighting for a while before deciding that they might have more in common with humans after all this time than their own supposed kind...
Aside from the witch-type neuroi, they don't seem to actually do much, besides maintain their hives, blow up anything that tries to get to close to one, and whatever it is they do to make more. For a bunch of scouts who've spent millennia watching humans go about their infinitely more varied lives, the prospect might seem a bit on the dull side - and depending on how utilitarian overall Neuroi behavior is, they may be expected to report to the disintegration chamber to be made into new dedicated combat units with an invasion in full swing. There's very little evidence for (or against) any motivation you may ascribe to them...
...showing MC the images of the Warlock project might have been requesting help to rescue the captured Shining Dodecahedron, now that I think of it, and that one lashing out at the humans who captured and tortured it, then made it destroy a bunch of other Neuroi before breaking free would be entirely understandable if you look at it that way.
