Franklins Bumble Bee Becomes Wild Ghost

No one has seen a Franklin’s Bumble Bee since 2006.
Ashland naturalist Pepper Trail writes in Jefferson Public Radio’s Jefferson Journalthat the rarest bumble bee in the world may have become a “wild ghost,” a name given to animals and plants so rare they are believed extinct.
Trail writes about searching in the Cascade-Siskiyou National Monument east of Ashland, Ore., with the last person to see a living Franklin’s Bumble Bee, Dr. Robbin Thorp of the University of California. The bee traditionally ranged an area of about 190 miles north to south and 70 miles east to west.
Trail said the search with Thorp failed to spot any Franklin’s Bumble Bees, but yielded other bumble bee species with descriptive names like Yellow-Faced, Yellow-Headed, Two-Form, Fuzzy-Horned and Cuckoo.
Thorp believes the spread of diseases from commercial bumble bee colonies may explain the gradual disappearance of the ghost bee since 1998.
Trail writes, “…I haven’t given up on Franklin’s.  Its small range is mostly in the Siskiyou Mountains, where there are plenty of meadows and little valleys far from roads that have never been surveyed.”
