A picture of a
teeny black and white bug
spotted in Portland and posted to a nature observation website earlier this month spurred a multiagency manhunt.
Species-watchers on the iNaturalist site grew concerned the small black creature with tiny white polka dots was a young spotted lanternfly — an
invasive species
native to Asia with the
potential to harm
Oregon’s
wine
, hops and fruit industries. Someone reported the possible sighting at Portland’s Colonel Summers Park to the Oregon Department of Agriculture, which launched an investigation.
After two visual surveys, the Oregon Department of Agriculture, Washington State Department of Agriculture and US Department of Agriculture Animal Plant Health and Inspection Service were
unable to find
any trace of the bug, so the lanternfly is still not considered to be present in Oregon. The agencies will keep monitoring the park in the coming weeks, the Department of Agriculture says.
The state is also asking Oregonians to keep an eye out and to report any sightings of the spotted lanternfly to the
Oregon Invasive Species hotline
with as much detail as possible, including pictures, location or even a specimen.
The immature, black and white version of the bug grows into a spotted planthopper with streaks of red down its wings.
The
bug eats
a range of plants including grapes, hops, fruits and hardwood trees, according to the US Department of Agriculture. It leaves behind a sugary fluid that causes mold and further damages plants. The critter was first spotted in the U.S. in 2014, in Pennsylvania, and has since infested 18 states, the department says.
While the Oregon Department of Agriculture has not found any living examples of the bug in Oregon yet, it has intercepted many dead adults and a live bunch of eggs on equipment coming into the state. The bug would have a negative impact on Oregon’s grapevine and nursery businesses, the state warns.
If you think you‘ve seen the spotted lanternfly, let the Oregon Department of Agriculture know by emailing plant-entomologists@oda.oregon.gov or calling (503) 986-4636.
Here’s
what to look for
and how to check that you‘re not seeing a different insect
commonly mistaken for
the spotted lanternfly.
