Every spring and fall the Bay Area gets swamped by tiny invaders - the gall wasps! These tiny creatures are gall-inducers - they "convince" plants to create little shelters on their leaves, stems, buds, and roots. Inside the gall, the larva develops, feeding on the plant until it's ready to become an adult.
