More than two inch long , the world ’s largest hornet carries a painful , sometimes lethal sting and an appetence for honey bees . It is also the newest insect invader of Washington state .
The Asian giant hornet , Vespa mandarinia , is plain , aver Susan Cobey , bee stock breeder with Washington State University ’s Department of Entomology .
“ They ’re like something out of a monster sketch with this huge lily-livered - orange face , ” she said .
“ It ’s a shockingly large hornet , ” added Todd Murray , WSU Extension entomologist and encroaching species specialiser . “ It ’s a health hazard , and more significantly , a important predator of honey bee . ”
Asian giant hornet , the world ’s largest species of hornet , was found late last twelvemonth in northwest Washington . WSU Extension scientists are partner with DoS agencies , beekeepers , and citizen to key out and report the invasive insect ( Photo courtesy WSDA ) .
Cobey , Murray and other WSU scientists are bracing for the giant hornet ’s issue this natural spring . Sighted for the first time in Washington last December , the hornet will start to become active in April . WSU researcher are working with the Washington State Department of Agriculture ( WSDA ) , beekeepers and citizen to find it , study it and help oneself pluck back its counterpane .
Voracious predatorIn the first - ever sightings in the U.S. , WSDA verified two reports of the Asiatic heavyweight hornet late last year near Blaine , Wash. and receive two probable , but unconfirmed reports , from site in Custer , Wash.
It is not known how or where the hornet first arrived in North America . dirt ball are frequently transported in international cargo and are sometimes transported deliberately .
At rest home in the timberland and low muckle of eastern and southeasterly Asia , the hornet feed on large insect , include native wasps and bees . In Japan , it lay waste to the European honey bee , which has no effective defence force .
Asian giant hornet are usually about 1.5 to 2 column inch in length , with an orangish - white-livered head and denude abdomen ( Photo courtesy WSDA ) .
The Asian giant hornet ’s lifespan cycles/second begins in April , when queens emerge from hibernation , feed on flora sap and fruit , and front for an underground dens to build up their nest . Once lay down , Colony grow and send off out workers to find food for thought and target .
Hornets are most destructive in the late summertime and early fall , when they are on the hunt for generator of protein to raise next year ’s faggot . V. mandarinia attack honey bee hives , kill grownup bee and devouring bee larva and pupa , while sharply defending the occupied dependency . Their stings are big and dreadful , with a strong neurotoxin . Multiple bunco game can stamp out humans , even if they are not allergic .
Forever changesGrowers depend on dearest bees to cross-pollinate many important northwest crop like apples , blueberries and cherries .
With the threat from hornet , “ apiculturist may be reluctant to bring their hives here , ” sound out Island County Extension scientist Tim Lawrence .
“ As a raw coinage go in our United States Department of State , this is the first drop in the pail , ” said Murray . Once established , invasive species like the spotty flank Drosophila melanogaster yield fly sheet or the zebra mussel make “ forever changes ” to local crops and ecologies .
“ Just like that , it ’s forever dissimilar , ” Murray said . “ We need to learn people how to recognize and name this hornet while populations are small , so that we can annihilate it while we still have a prospect . ”
Beekeepers , WSU Master Gardener volunteers and other Extension guest are often the first detectors of invading metal money . WSU scientists are now diffuse awareness of the hornet to citizens and developing a fact sheet to help multitude identify and safely find the insects .
As partners with the Washington Invasive Species Council , they also urge citizen to download theWA Invasives smartphone appfor quick reporting of sighting .
“ We need to get the word out , ” said Lawrence . “ We involve to get a readable image of what ’s happening out there , and have hoi polloi report it as shortly as potential . ”
other detection , riotous eradicationScientists with the WSDA Pest Program are taking the principal on finding , trapping and eradicating the pest . WSDA will begin trap for queen this fountain , with a focus on Whatcom , Skagit , San Juan , and Island counties .
“ Our focus is on detection and eradication , ” pronounce WSDA entomologist Chris Looney .

The agency plans to join forces with local apiarist and WSU Extension scientists and entomologists with WSU rivet its elbow grease on management advice for beekeepers .
Regular beekeeping case are piteous auspices against this hornet ’s bunko game , said Looney . WSDA ordered extra reinforce suits from China .
“ Do n’t seek to take them out yourself if you see them , ” he said . “ If you get into them , turn tail away , then call us ! It is really important for us to know of every sighting , if we ’re going to have any hope of eradication . ”
