This one has distinctive black speckled granularity on its dorsal abdominal surface. Lividus is also grainy, but lacks the black speckled grain this one shows. Stout spinules on lateral margins of S8,9 visible in ventral abdomen picture.

I am confident about the ID: habitat was pond, small nymph size, abundance of adults at this location. I think couplet 9 (pg. 256, Tennessen), "weakly granular" is not applicable in our area. I have reared exilis from this area and I find that they are quite granular at 25X.

After mating, the female began ovipositing and then crawled into the water and continued ovipositing and remained submerged at a depth of about 15cm for 4 minuted before disappearing. I did not see her resurface.
