A Poem and a Riddle

In the north hemisphere it is a constellation.
Then there is the devil also known as Satan.
A serpent that flies above the ground.
A person that’s fierce, where fire abounds
A plant known as the African Arum.
And also a species of palm.
A genus of insects, scientifically known as Libellula.
Now what is the title of this poem, give a explanation.
