Buggys should have some kind of idle animation when they're commanded to stay put or if they haven't done anything in a while. It could just make them feel more realistic.
I love seeing bugs fighting in the world naturally so I think more types of bugs should fight one another on occasion
Lastly I feel like certain bugs need more of a presence in the world, like bees feel really rare and the red ants don't really feel very notable in the world. For the ants I can see that making sense seeing as one of the queen ants seems like it was killed by a spider but in the future for other ant variants, more of a presence would be fun.
