A Riddle (?): The Desert and the Cricket are Friends of Mine

Sugar in my veins;
I can freeze before the thaw.

When it’s dry… oh so very dry,
my body sheds it’s skin,
into a waterproof house,

And when the river flows,
you will hear my soft echoes
into the night.

In land or water or both;
what am I, when i’m proof
of the living dead?
