What is this?
It was in a quiet pool at the edge of a mountain stream. We photographed it while still in the water.

Dear GNB Arnold,
This is one of the Giant Water Bugs in the family Belostomatidae, and we believe it is a member of the genus Abedus that is found in the western states. The parenting behavior of this genus is quite interesting. The female cements the eggs to the back of the male who carries them about until they hatch. It is a rare instance of paternal parenting among insects. See BugGuide for additional information on the genus Abedus.
