Most Haunted moth

I have captured an orb in my camera
In the garden quite late at night
I should not boast but It's obviously a ghost,
And not something else caught in a light

Though my camera is rather expensive
And the picture I've taken is blurred
I will give you a hint, you really should squint
You will see that a haunt has occurred

And my cameras flash was still working
 and the weather was raining and cool
I scream and complain. for it wasn't the rain
But a poltergeist, ghost or a ghoul 

Though I noticed a thing that then happened
When this ghost came to fill me with dread
A bat did appear, at it came rather near
And snatched the ghost over my head

Yeah. It a Moth isn't it?
