It starts with one, maybe a few, hitchhiking bugs.
They arrive attached to an exotic plant or in the moist bottom of a vase after crossing a border or an ocean or the sky.
Sometimes – maybe even most of the time – the invasive creature dies off soon after landing in Southern California. But a few find the region to their liking, thriving with no natural predators and abundant food. A few even gain such a powerful foothold in their new home that they become threats to crops and forests and industries.
