(Reuters) – A North American bumblebee species that all but vanished from about half of its natural range has re-emerged in Washington state, delighting scientists who voiced optimism the insect might eventually make a recovery in the Pacific Northwest.
Entomologists and bee enthusiasts in recent weeks have photographed several specimens of the long-absent western bumblebee – known to scientists as Bombus occidentalis – buzzing among flower blossoms in a suburban park north of Seattle.
"It's a pretty big deal," said Rich Hatfield, a biologist for the Oregon-based Xerces Society for Invertebrate Conservation, which documents and reports such findings.
"It gives us hope that we can do some conservation work, and perhaps the species has a chance at repopulating its range," he told Reuters this week.
The multiple sightings, including observations of several queens, are evidence of western bumblebee colonies in the area, although it hardly proves the species has returned in force and or that it will thrive in the region, Hatfield said.
Last year, a single western bumblebee, recognized by its distinctive white-banded bottom, was discovered by an insect enthusiast in her mother's garden in suburban Brier, Washington. It was the first sighting in Washington state west of the Cascades in well over a decade.
Her sighting was confirmed earlier this month as more than an isolated incident when Will Peterman, 42, a freelance writer-photographer and self-described "bee nerd" from Seattle, ventured into a park in Brier to capture his own shots of Bombus occidentalis foraging in blackberry bushes for nectar and pollen.
