In the spring, Tegeticula spp. emerge from cocoons and fly to nearby yucca plants and mate. The female then deposits eggs into the yucca plant ovary and deposits a pollen ball on the flower's stigma, pollinating the plant. The larva, usually one or two, hatch inside the developing ovary during late spring and summer and feed on the maturing seeds through the summer and fall. The larva bores out of the fruit upon maturity and creates a cocoon in the soil. The adult then emerges up to one year later.
