Wednesday, July 8, 2020 The Nugget Newspaper, Sisters, Oregon Tales from a Sisters Naturalist by Jim Anderson Invasion of the giant bee snatchers! The Xerces Society, one of the leading world-wide insect conservation organi- zations, put on a four-hour Bumble Bee Atlas webinar a couple of weeks back. Right in the middle of it, the presenter, Professor Rich Hatfield, paused in his recitation on bumble bees and placed an illustration of the Asian giant wasp on the screen, saying: <This is not one of our local bum- ble bees, it is the <murder wasp= that9s hit the head- lines recently. The reason I put this in my program is because I have heard of mis- informed people killing our native bumble bees, think- ing they are the infamous invader, the Asian yellow- faced wasp.= Please, Good People, be sure of what you are killing before you do it. Our native bumble bees are among the most important plant polli- nators on this beautiful old Earth we call home. They have enough trouble staying alive without being killed because they are being mis- taken for the alien Asian giant wasp. As near as I can discover, about 15 of these giant invaders have been observed in the USA proper, and that was up near Tacoma, Washington. If a group somehow got trapped in a shipping container in the home range of these giants, and then got loose when they arrived in the Seattle docks, they could have flown to the Tacoma area, but& Entomologists at Washington State University (WSU) are looking into the sudden appearance of these giant wasps, Vespa manda- rinia. The invaders are as long as a child9s little finger 4 the world9s largest wasps 4 and they are fearsome- looking creatures. They have a sting that can kill humans if one is stung multiple times, earning them their nickname, <mur- der wasps.= Beekeepers in the area of discovery have reported piles of dead bees with their heads ripped off, an alarming sight and appar- ently the sign of the giant wasp9s actions. Obviously, the U.S. doesn9t need another factor endangering our native pollinators and the honey business. Back in their home range, these monsters are found in the forests and low mountains of eastern and southeast Asia. They live in dens in the ground (as do our native bumble bees), and feed on large insects, including native wasps and the European honey bees, which they are devastating in Japan. The newest report on the wasp9s presence in the U.S. came in at the end of May from the little town of Custer, Washington, near the British Columbia bor- der. The monstrous insect was found dead and has been reported by WSU to be a mated queen, which to me, as a former bee-keeper, spells bad news. She may have come from a colony of her own, or 4 worse news 4 she may have come from a colony already spreading out and she was looking for a new place to build a colony. If so, she may have sis- ters out looking for the same thing& While they are not usu- ally aggressive towards humans, they can be if pro- voked, claim WSU scien- tists. Their stingers are big and painful, and inject a potent neurotoxin. So, what do you do if you spot an Asian giant wasp? I would call our local county health department (541-322- 7400).

No matter how loathsome it may appear, please do not dispose of it; save it in a jar. The last thing we want to see happen is for these huge invaders to get their feet on the ground 4 literally 4 and reproduce.
