Water Scorpion on wall

I've been informed that this is a “water scorpion” – it hangs upside down in the water column, with its butt sticking out of the water, and breaths air through its ass (pretty cool!)
I photographed it on a slightly damp wall on a building over the road from the vegetation just in front of the sea at Bodden Town, Grand Cayman, Cayman Islands. Second pic shows how large the creature appears to be (approx. 2 1/2" long.)
Beautiful 'face mask' markings on back, looks like evil, grinning face.

I agree it is superficially

I agree it is superficially like a water scorpion, but it is about 5x as big as Nepa cinerea. I suspect it is a terrestrial bug, as it doesn't seem to have the breathing tube of a water scorpion.

These belong to the family Belostomatidae, they are interesting for many reasons, including their size, their excruciatingly painful bite, that they show parental care of their young, and are used as a food source by humans! See:
