Somebody's theory - sorry I forgot the name - Russian ?? - from the early 1900s
maintains that many insects within a species naturally vary in regard to the
latitude where they are found (and adapted). This fits the size and shape of
the AHB from tropical Africa, as I remember. He is usually quoted in relation
to body size, wing length, and leg length. I will ask around here tomorrow -
I'm sure Hayward Spangler knows the reference.
