Q.E.D. (1982)

The 300 Million Years War (1985x3)

:

Minefields, poison gas, hired mercenaries, early-warning systems - it's no holds barred in the never-ending battle between two of nature's superpowers: the insects and the plants. Q.E.D. uncovers a microscopic world of conflict where thousands of insects lay siege to a single tree. Unable to move, plants retaliate with their arsenal of chemical weapons. There are few clear victories, but one thing is certain - plants are not pacifists.
