Boatman Pic actually Notonecta?
September 28, 2010
Hello, Friends of the Bugs,
While trying to ID a bug that had landed on our deck here in Edmonds,WA, I discovered that you have the same picture on your site under two different headings/labels.  It comes up under “Water Boatman are Edible” when “Boatman” is typed into the search box.  Your answer to that post was to say it was Corixidae.  The picture matches “my” bug exactly, and I had also come to the tentative conclusion after initially looking in Bug Guide, of Corixidae, but wasn’t convinced.  However, on BugGuide I happened to see another pic that also matched, was mislabeled as Corixidae, and someone had posted that it was Notonecta.  Looking further online, I agree 100%.
If I type Notonecta or Backswimmer into your search box, it comes up with a post titled “Backswimmer” which appears to be the exact picture, this time correctly IDd as Notonecta.  I thought you’d like to know so a note can be added (or however you want to deal with it, if at all) to the Boatman one, correcting the ID.  It might be confusing to some, such as myself, who might not accidently happen upon the correct ID and be thinking it is a Boatman.  I think many folks, like myself, might initially do a search for Boatman upon finding one of these bugs, since I was not familiar with the existence of Backswimmers.  But now I know, and I would have really wondered how a waterbug got on my 2nd story deck, except you explained they can fly well.  The 7/22/10 pic of a Backswimmer swimming (on its back, of course) highlighting the abdominal hairs is especially nice.
I did not bother to submit all the pics I took because I found the ID, as you already have several pictures, including one from 2005. I only attached one for reference.  Later, the Backswimmer had flown away.  Thanks again for such a great site.
Cheers, Dee Warnock


Hi Dee,
Thanks for bringing this to our attention.  We did not realize that Baffled in Santa Cruz submitted the exact same image as Jason, and that Baffled in Santa Cruz had taken the original photo from our site.  We have included your letter as an update on the Backswimmer that was misidentified as a Water Boatman as well as making it a unique posting since we are certain of the authorship of your photograph.  Since the postings with the same images came in several months apart, we didn’t realize that Baffled had sent in Jason’s photo.  Because we want to maintain some sense of honesty and integrity to our postings, we have recently added this statement to our form:  “Also, you swear that you either took the photo(s) yourself or have explicit permission from the photographer or copyright holder to use the image.
”  We really like the common name of Water Wasp given to Backswimmers since their stabbing bite is quite painful.
