I think this is a Giant Water Bug in the genus Abedus, but I’ve not been able to find images of Abedus or its relatives showing the paddle shape on the end of the front legs. Thus, I’m wondering if my ID is incorrect. This is about 2.5 cm long and was netted from a riparian pool

We agree that this is a Giant Water Bug in the genus Abedus. Most photos do not provide a good view of the raptorial front legs, however we did find an image on BugGuide that shows the well developed forelegs. Though not as impressively large as the Eastern Toe-Biter, Western Giant Water Bugs in the genus Abedus are fascinating creatures. The male carries the eggs on his backwhere they have been cemented by the female, providing some degree of paternal care, a relative rarity in the insect world.
Thanks once again, Daniel. I’ll look at Bugguide again – I missed the
image you found.
