A Nocturnal Visitor

A week of rain brought an unusual visitor to our living room window night after night.  This is the window above the air conditioner so there is no screen.

 As tiny as he was, I still can't believe he fit between where the windows meet.  By 8 every morning, he'd scooch himself down and out.  The rain ended yesterday afternoon, and sadly he did not come back last night. 

To give you some perspective as to his size, in this picture above, looking right below the frog, there is a raised white section with a black spot.  The white piece is part of the window lock mechanism and is 1 3/4 inches long.
