Water Boatmen  (two photos)
Corixidae

These aquatic insects are called Water Boatmen because they row through the water with those
long legs.  They also come out onto land like this one is doing.  
They can remain submerged for
hours because they trap air in pockets on their body.  They are predators. I found these at Garr
Ranch on Antelope Island and this is the first time I had ever seen them.  There are similar insects
called Backswimmers that can bite but the Water Boatmen do not.  Backswimmers have also
been found in this pond. © Carol Davis, 3-4-2005
