Verified: the omnivore wipes them out in 40 generations in my test with both starting on grassland and no other animals in the simulation.
on the other hand:
if a specialized killer of the omnivore is added (weapons 2, speed 2, nothing else) then it eventually (85 generations) killed off the omnivore in my simulation and was able to subsequently co-exist with the minimal seed-eater, which it also predated but not enough to crash the population. Theoretically, the omnivore could move somewhere else, but no such populations got established in my simulation.
(edit: post bugfix, this was 38 generations and 114 generations. The omnivore did spread to other biomes, but its nemesis spread too and wiped out the colonies before dying out in the biomes without the mimimalist)
I also came up with this strategy (I called them weevils), but I think it’s beaten by a small omnivore that eats both seeds and weevils/locusts.
