Asian hornet in Ontario Oregon? #874549

Asked June 24, 2024, 10:21 PM EDT

Not sure if I am asking the right people about this, but I found this dead in my driveway on NW 4th Ave. In Ontario Oregon. I have never seen a hornet/wasp of this size and marking locally. The only comparison I can make is with the Asian hornet.

Malheur County Oregon

Hi Darrell,
Thanks for being alert and on the look-out for Asian giant hornets (also called northern giant hornets and murder hornets, Vespa mandarina).

Luckily, the wasp you found is a native cicada-killer wasp (Sphecius grandis or Sphecius convallis--I can't tell which species from the photo).
Female cicada-killer wasps catch and paralyze cicadas, which they bring back to their nests to provide food for their larvae.
Here is a link with more information about cicada-killers...

Asian giant hornets are similar in size to cicada-killers, but the heads of Asian giant hornets are larger and paler in color.

Here is a link to a great webpage from the Washington Department of Agriculture that show side-by-side pics of Asian giant hornets (called northern giant hornets here) and some similar looking insects...

Thank you so much for the rapid and informative response. Something of a relief, truth be told. I wasn't looking forward to the damage to our local honey bee population.
