They sound more like a real life hivemind than something like the zerg.

That's already a nice improvement from what I feared you may do and I hope that further revisions and IC will differentiate them more from being mindless drones as time goes on.

I am curious as to why they have space travel and what the vehicles are as they don't seem to have guns and seem mostly docile beyond defensiveness of the queens (do they have actual authority or are they more or less factories that don't actually manage anything?).

Asymmetrical conflict is a major element to the scenario and it would destroy lots of variation in the types of potential scenarios for how relationships between factions work out if every native species manages to independently develop space travel and makes symmetrical warfare the norm.

Though you don't specify their means of space travel much, so it could well just be in the form of colonial seed ships, something based on some symbiotic relationship with custodians or something else.  Space travel is optional in this NRP and you can always find reasons to have spaceships outsourced/stolen from another player's faction.

I should have specificed the name/subject thing.

Name is what you intend to call them and subject was misleading.

Type or Class may work better.  Basically what you classify them as in regards to lore content on the question of if they are species, a faction, a individual, some non-state actor and so on.
