I kind of did this once. Basically, make the warrior bugs biologically incapable of fear, which makes them seem quite alien, but also lets them act heroically and bravely (from a human perspective). Yet, they can still talk to humans, maybe through a voicebox machine thingy, so they're characters that can be really interacted with. It's so common to have a knightly character archetype of some kind in space opera (Jedi, B5's Rangers, Covenant Elites); why not let the bugs take that role?
TL:DR; Samurai Space Bugs
As a hive society, the other groups are selfless, too, in their own ways. The workers will work long, long hours and never complain. They don't really use money in their internal economy; bugs are provided for by the hive and produce as much as they can. It works for them, while communism failed for us, because they aren't self-centered in the same way.
The Queen of each hive (each of them operating loosely independently) is god, mother and queen to everyone in the hive, so she's a major national symbol. Bug hives will have wars with each other, but while they'll happily kill each other for a resource, it's not personal when only warriors die. Killing workers is extremely provocative and killing a Queen is something that happens very, very rarely, and is tantamount to genocide, since a good chunk of the surviving population will kill themselves rather than live on, and most of the rest will spend the rest of their lives hunting and fighting the perpetrators.
I could go on, but these are all ideas I worked in when I ran a BESM space opera game with a bug race allied to humanity.
