Predacious Diving Beetle (Cybister fimbriolatus)

Another interesting beetle adaptation. The predacious diving beetle lives and hunts underwater, but when it needs to relocate, it can take to the air until it locates another suitable body of water. These beetles are large enough to kill and consume small fish, however they typically hunt other invertebrates.

Whirligig Beetle, or Gyrinidae Beetle, (Dineutus sp)

Small and fast moving, these little aquatic beetles often swim in agitated circular patterns. They are so adept at avoiding predators, that getting close to one can be quite a challenge. Seen in detail, they have a surprising beauty and personality.

They have divided compound eyes. The upper part of the eye sees above water while the lower part of the eye can see under the surface.
