Supporting Evidence
Photo of my evidence.
This water bug has one pair of forelegs that are wide set and elbowed as Giant water bugs are known to have.
Photo of my evidence.
Wings overlap to form an x-shape. We know that Giant water bugs have this feature.
Photo of my evidence.
Has a pair of appendages at the end of its abdomen. This distinguishes it from other species of water bug.

Comments

Great pics again! I have only seen one of these- looks like this will be a site to visit for fly fishing in the spring! I appreciate that you included where you were finding your macros- why do you think you found bigger species in the calm water?

I think it's probably because they don't have the right equipment to latch onto the rocks in moving water. In the case of the Giant Water Bug, it needs to come to the surface to breathe so that might affect it's habitat choice too.

Thanks for your comment!

Hi again,

It looks like your coordinates are off on this observation as well. Please comment below with the correct coordinates (in decimal degrees) and we will update your observation.

Thanks!
