While spending an evening at the edge of a remote sand dune in the middle of Murray-Sunset National Park, amongst the insects on the sand attracted to our light I was surprised to find quite a few Water Boatmen.
These are insects that one expects to find in water and here they were, many kilometres from any body of water, or even a puddle, in an arid mallee and spinifex environment.
I later read that Water Boatmen are actually excellent fliers, able to easily move from one water body to another.* Well that seems to be true. I'm very impressed, these insects are only a few millimetres long.
