I'm sitting with two professors in an office in the Agricultural Science Building at the University of Idaho in Moscow, two of only a few people in the world who have had up close and personal experiences with the giant white earth worm of the Palouse.
I confess to them immediately that I am a complete ignoramus when it comes to worms, especially this worm. James "Ding" Johnson, head of the plant, soil, and entomological sciences department, assures me that when they tell me everything they know, I will leave almost as ignorant as when I arrived. Almost as ignorant as they are.
The giant white earth worm of the Palouse sounds like a hoax or a Bigfoot-style myth. But unlike Bigfoot, Driloleirus americanus has been found alive by scientists. The rare earthworm reputedly grows up to three feet in length and was once said to be "abundant" in the fertile rolling hills of the Palouse, a rich agricultural region encompassing some two million acres of southeastern Washington and northern Idaho. The Palouse was once uncultivated prairie with thick deposits of topsoil. The worms dig deep – maybe as deep as 15 or 20 feet – and they are white, like albinos, instead of the more familiar pink. They reportedly give off a smell like lillies and will spit at you if provoked.
Ding Johnson has probably seen more of the living worms than any man alive. In 1988, he and a graduate student named Paul Johnson (no relation) – both of them insect, not worm, experts – were looking for beetles at a place called Moscow Mountain, a peak that rises about 2,500 feet above Moscow, Idaho. Its forested slopes aren't like the smooth Palouse hills, and not the kind of habitat thought to be white worm-friendly. But the two Johnsons flipped over a chunk of moss and found six of the rare worms. Most of them escaped, but two were captured. Johnson has sinus problems and never smelled the lilly scent, but he says one did spit at him. Yes, worms have mouths. Anuses too.
The giant white's existence in sciences dates to 1898, when one was sent to experts for identification. Through the decades, there were stories and anecdotes about worm finds, mostly by non-scientists. That supposedly three-foot-long Palouse worm? Johnson says it was measured after a kid had been swinging it around like a lariat, so the truth of its size might literally have been stretched.
In 1978, a worm expert from Oregon found two. A decade after that was the Johnsons' bonanza. Then for 17 years, all was quiet on the worm front, until 2005, when a University of Idaho grad student named Yaniria Sanchez-de Leon, digging for worms in a remnant of Palouse prairie at a place called Smoot Hill, reserved for research by Washington State University, found one of the rare white creatures. Well, she found two halves of it, because she'd accidentally cut it in half with her shovel. It was an important find tinged with tragedy, kind of like finding a Sasquatch as road kill.
Nevertheless, the find generated excitement in the scientific community. The worm corpse was sent to the Northwest's foremost worm expert, the guy who found a couple of great whites in 1978. William Fender-Westwind is a true scientific character of the old school. Widely respected, he is no academic but a man who carries on a family tradition of amateur science. His mother is also a worm expert with a huge collection of specimens kept in a shed (claimed to be the largest such collection outside the Smithsonian). Her husband, a postman, was a recognized authority on soldier beetles.
Fender-Westwind is also obsessed with finding the great white worm's cousin, the giant earthworm of Oregon, which has also proven elusive in recent years. (Sierra magazine had an excellent profile of Fender-Westwind in 2003.) Despite his amateur status, Fender-Westwind is the go-to guy for earthworm answers. Ding Johnson says that worm and insect people stick together. "Neither is a social plus," he says. It was Fender-Westwind who autopsied Sanchez-de Leon's find and confirmed, in 2006, that it was indeed a great white.
