Rare Beetle Threatened by Habitat Loss, ORVs, Sea-Level Rise

PORTLAND, Ore.; Wednesday, September 29, 2021---In response to a petition filed by the Center for Biological Diversity and the Xerces Society for Invertebrate Conservation, the U.S. Fish and Wildlife Service announced today that the imperiled Siuslaw hairy-necked tiger beetle may qualify for protection under the Endangered Species Act.

The tiger beetles once lived on coastal beaches from Northern California to Washington but have been lost from most of those places. The most recent surveys found them at only 17 sites in Oregon; in Washington, they’re only known to survive at three sites. At nearly all sites, fewer than 50 individuals were located.

The species is severely threatened by habitat loss and destruction caused by off-road vehicles (ORVs), climate change, coastal erosion and trampling by beachgoers. It’s also at risk from inbreeding and invasive species. Endangered Species Act protection will ensure that the federal and state agencies that manage the beetle’s remaining populations protect it from these threats.

“As unspoiled stretches of the Oregon coast vanish to development and the impacts of climate change, we risk losing unique species like the tiger beetle,” said Quinn Read, Oregon policy director at the Center for Biological Diversity. “I’m hoping Endangered Species Act protection can give these beautiful insects and their habitat a fighting chance of survival.”

Seven of 17 remaining beetle sites in Oregon are concentrated along a 10.5-mile stretch of the New River Area of Critical Environmental Concern, one of the last remaining wild places along the Oregon coast. Other Oregon sites occur on the Siuslaw National Forest in the Oregon Dunes National Recreation Area, one of the most popular areas for ORV use in the world, as well as state parks in Oregon and Washington.

“The Siuslaw hairy-necked tiger beetle is now one step closer to protection,” said Sarina Jepsen, endangered species director at the Xerces Society. “This extraordinary beetle only lives at freshwater outflows into the Pacific Ocean that remain largely untouched. Because it spends part of its life burrowed in the sand, it’s particularly vulnerable to trampling, ORV use and other earth-moving activities.”

Named after the Siuslaw people, who trace their ancestry back to the aboriginal inhabitants of the South-Central coast of Oregon, the Siuslaw hairy-necked tiger beetle hunts its prey in coastal areas where fresh water meets ocean beaches.

The tiger beetle is a fierce predator as both an adult and a larva. Adults are fast and mobile hunters who run across the sand in short bursts or short, hopping flights to chase prey. They run so fast that they need to stop after each burst to visually relocate their prey before continuing the pursuit. Their larvae are “sit and wait” hunters who keep their heads flush with the sand surface and, when prey walks by, reach up to half their body length out of their burrows and grab the prey with their jaws, then drag it to the bottom of the burrow to consume it.
