Male Argia sedula

This species was abundant along the edges of the muddy ponds that had flooded from the recent storms.

A good deal of vegetation on the downstream margin of the pond had been displaced, lifted out of the water, drying near the shoreline. Surely those clumps of vegetation (mostly Alternanthera philoxeroides) housed some eggs or nymphs that had been laid so far this year.

I was wondering if there is some release mechanism/behavior when the rate of water exceeds a certain value or if the inhabitants in such floods are just doomed.
