The average length of a glasswing is only 1.1" to 1.3". Their wingspan is 2.2" to 2.4". Because of
their small size, they are very difficult to find in the Butterfly Garden. Fortunately,
one of the gallery guides told me that she had seen two of them that day
and took me to an area among some leaves where one of them
was resting.
