Anyway trees in a forest are adapted to insects eating their leaves and fruits, just as the insects are adapted to the trees themselves. This is the result of natural selection- any insect damaging a tree means that if individual trees can resist the damage they will be more likely to produce the next generation and this is how species evolve together. So you see, the insects dont need to modify their behaviour as evolution will remove them if their behaviour doesnt fit in with their ecosystem (ie theyll starve if their behaviour means there is no more food) and evolution also allows other species to adapt to the behaviour.of course they have brains.......
The insects won't be thinking about this either. Populations are limited by resources and when resources run low, they suffer from starvation. Over time a species finds a balance beween itself and the other species in the ecosystem (not just animals but plants, fungi etc). We see imbalance when a new species comes into the environment and the other species are not adapted to it.

i think they are dependent each other.
Insect brains do not think. They only release hormones and interpret what the compound eyes see. And the insect world isn't brutal. Many other "worlds" are brutal. Lions eat lion cubs. Orkas play with seals brutally before killing them. My cat slowly kills mice and lizards and doesn't eat them. Humans too we still kill one another and die slow painful deaths. Even birds are brutal hawks drop rabbits onto the ground from way high to kill it. So insects are by far normal with how they get squashed trapped and eaten.
OMG arachnids and insects are vastly I mean a huge grand canyon gap of differences. The only thing insects and arachnids have in common is an exoskeleton.
And insects won't preserve a habitat. If no predators existed they would eat all the vegetation away and starve. No brain power.
Entomologist-people who study insects "insect scientist"
Arachnologist- people who study arachnids
And insects don't think ever. Even if we observe and think they are thinking they really aren't.
