Like Corixa, but not quite...
What be these bugs?
Always quit when you're through.

I believe them to be Backswimmers, a close relative of Waterboatmen. Not Aquatic Beetles, but rather, Waterbugs.

They are true bugs (Hemiptera) within the Belostomatidae. Cannot see enough to decide genus. Be a little careful - they can "bite" - pierce ya with a big dull needle :-) Here is a link to a pic of the poker -

The first one definitely looks like a Backswimmer (Family Notonectidae).

Hi Dave-

Be a little careful - they can "bite" - pierce ya with a big dull needle :-)


Yeah, ain't that the truth. Here is a photo I took of one several years ago:



The needle part of the beak is used to inject a toxic tissue-dissolving enzyme into the victim, which is shortly followed by sucking out all of the now dead prey's dissolved tissue. Doesn't sound like a particularly endearing experience. :-)

Roger - I had one hit the heel of my hand. I didn't leave it there long enough to suck! Not that much scientific curiosity....... No parts fell off but took a couple weeks to heal. That ain't no mosquito bite.
