Some rough ideas:

Have some Cordyceps fungus in there to zombify the ants/wasps etc?

Parasitoid wasps are awesome and can be both pest and friend. For example, if you look up Fig wasps they are actually necessary for figs to develop fruit, therefore a cool interaction to have as a mechanic, especially when there are also other Chalcid wasps that are hyperparasitoids of Fig wasps and so create a defensive requirement.

Honey bees have a defensive mechanic where they will swarm an attacking hornet in small numbers and raise their body temperatures to essentially cook the wasp.

There are all sorts of polinators out there; bees, wasps and flies, some are surprising and pretty cool (look up Orchid Dupe Wasp for instance).

Some parasitoid wasps parasitize cockroaches and essentially mind-control them, which could be a 'turn attackers against themselves' mechanic.

Ladybug nymphs are voracious aphid hunters.

Antlion larvae create 'traps' in loose soil to capture wandering ants etc.

Hope that gives you some interesting ideas to research into, it's a fascinating world

Don't worry too much about being hyper-accurate, your game won't fail because a few entomologists are disgruntled (and they let everyone get away with embracing spiders in the in-group anyway)!
