They may prefer not to be noticed.

If anyone could travel at the speed of light they would neither
want to nor need to. Why would they bother? To go on an exotic
holiday? To conquer a few more planets? Suppress a few more
billions to their [human] way of thinking?

Yawn.

Nothing is _that_ exotic when you've already seen everything
there is to see. A wet planet packed with backward worker ants
all pretending to be a higher species?

Yawn.

"Conquering the galaxy" is a very human viewpoint. Nobody else is
that daft. Nor that sociopathically aggressive.

When did you meet, "them" to have determined this?

Simple logic. Any species with the capacity for light travel must
[surely] have worn out the age old problem of lack of resources?

Not necessarily - their main motivation for moving to a new planetary
system may well be because they have exhausted or polluted their last.
Or that their sun has reached its "best before" date.

What is fairly certain however is that to master near lightspeed drive
they will have technologies that are potentially way more destructive
than anything that we can imagine. So it seems likely that they are
pretty civilised and able to negotiate amongst themselves.

How they view the lesser lifeforms they encounter in places where they
want the resources might depend on how benevolent (or otherwise) they
are towards other species. Insect like intelligent lifeforms might be
unimpressed with how we treat their kind on this planet for example.
