It's a bird, it's a boat, it's a Predaceous Diving Beetle!

It can fly, walk and swim, and they live all over Canada. While that may sound like a aquatic bird, what we're describing is actually Predaceous Diving beetles. These beetles are commonly seen in many ponds and slow moving streams. While they are proficient swimmers, they can still use their wings to fly between ponds. Like their name suggest, they are dangerous predators to other insects and small fish.

They are quite adept in the water, swimming akin to a frog with both back legs moving at the same time. Before diving into the water, they can collect air under their wings, making them able to breathe underwater for a period. However, it can be hard for these beetles to get out of the water and break the surface tension. To counter this, they will use ingested water and quickly expel it out of their rectum to help propel them out of the water. That's a creative way to use water!
