insects. Although the name pond skater is frequently used to refer specifically to the largest members of this group, belonging to the family Gerridae, here we will use it to refer to all surface-dwelling insects of the order Hemiptera .

backswimmer
The backswimmer as the name implies swims upside down on or near the surface of the water with their legs up!
Structural
The backswimmer's keel-shaped back and powerful legs help it swim after its prey of small aquatic animals and escape its enemies.
They have little "hairs" that cover its body to hold the air bubble for breathing.
They are predators (stalking other insects), with sucking mouthparts and often snatch bugs on the water surface, drag them under and devour them.
Behavioural
To breathe underwater, they carry a silvery air bubble at the tip of its abdomen. This bubble is held in place by the little "hairs" that cover its body. When the air in the bubble is used up, the insect rises to the surface and with a quick, somersaulting motion captures a new bubble.
