Crackers

[Niklas Wahlberg]

Hi,
    I had my first experience with crackers (Hamadryas) in Brazil last 
year, quite amazing! I don't remember the species, but they were cracking 
all over the place. The butterflies cracked everytime I saw them take off 
from the trunk of a tree, where they rested. I was astounded since I'd 
never even heard tell of butterflies making sounds. But alas I have no 
other information as to how they make these sounds.

Cheers,
Niklas
