From the San Francisco Chronicle:
Jack Chambers held up a handful of rich, black compost.
Hundreds of aptly named red wriggler worms were writhing within it.
"These worms are made for composting," he said proudly, giving their Latin name - Eisenia fetida. "This was pure cow manure just weeks ago - notice that there is no smell and no flies."
Chambers, a pilot for Delta Air Lines, has done double duty as a worm farmer for the past 18 years. He and his wife, Lois Chambers, own the Sonoma Valley Worm Farm (http://www.sonomavalleyworms.comwww.sonomavalleyworms.com), which produces "vermicompost" (worm waste and other organic material) for vineyards and farms, and sells worms by mail order throughout the Bay Area.
