Hi Blake,
This is an Ichneumon. We are inclined to guess that it is a Megarhyssa species, but it does not match any specimens on BugGuide. In 2004, we received a nearly identical specimen that Eric Eaton identified as Megarhyssa nortoni. The specimens pictured on BugGuide are brown and yellow, not black and white, which has us puzzled. There is also a photo posted on an Australian website where Megarhyssa nortoni has been introduced as a biological control agent for the European Wood Wasp, Sirex noctilio. Eric Eaton quickly wrote back with this comment: “Hi, Daniel: Well, I’m wondering now if the ichneumons are even in the GENUS Megarhyssa! I can’t be absolutely positive. I know there are sizable ichneumons in other genera that closely resemble Megarhyssa, especially in the western U.S. Eric”

  1. We had one identical to this wasp, with the black and white, fly in to our house last night (June 12, 2014, Lake Forest Park, Washington (just west of Brier, Washington where this specimen was found)). This is the only matching photo I have found to date. I do have photos for anyone interested.
