#metrobates hesperius

[platycryptus]

Metrobates hesperius is a small, wingless water strider that forms large swarms on the surface of lakes and rivers, feeding on insects that fall in.

Their swarming behavior and erratic movements might help them avoid being picked out as a target by predators, like the dragonflies I saw flying past and trying to pluck them from the water.
