SCV Outdoor Report: A Moth On A Mission

By Wendy Langhans

 

Earlier this week, I was driving along a winding mountain road in the Angeles National Forest, in a hurry to get to my destination.  It was early evening, a time when the sun-drenched colors of midday were fading to sepia.  I could see the tall, white, spiky stalks of Chaparral Yucca across the canyon, as they stood out against an indistinct backdrop of vegetation.

I was struck by how brightly the Yucca glowed, radiant in the twilight.  “So that’s why they call them ‘Our Lord’s Candle'”, I thought.  “They DO gleam like a candles on a dimly lit table.”

But I wasn’t the only creature traveling through these mountains at twilight.  The female Yucca moth, Tegeticula maculata, was also out and about, in search of the Yucca whipplei.  The moth and the plant are involved in a symbiotic relationship; each one needs the other to survive.  The Yucca plant needs the Yucca moth to pollinate its flowers.  In return, the Yucca plant provides an incubator for her eggs and seeds to feed the larvae of the Yucca moth.

The Yucca moth sets out at night, gathering pollen from various Yucca flowers and shaping it into a large ball (larger than her head).  Then she flies to another Yucca plant, climbs inside a flower blossom, and inserts 3-5 of her eggs into the ovary of that blossom.  Next, she takes a portion of the pollen ball and inserts it into the stigma of that same blossom, thereby ensuring pollination and the production of 150-200 seeds.  Later, her eggs will hatch into larvae that will feed on some of those seeds.

 

The Yucca moth has a tight schedule – three nights to lay 100 eggs.  That night I also had a tight schedule, with “promises to keep and miles to go before I sleep”.  I guess we were both on a mission that night.
