sense of hearing

[Andrea Hoffmann]

hi folks,

i've read in one of my books that certain families of butterflies have a
sense of hearing and they can even pick up ultrasound.

i'd now like to know which families have this sense of hearing? and is
there any literature that deals with the butterflies' senses? or any other
pointers on this topic?

i've got quite a number of books here but none of them elaborates on that
topic.

thanks in advance for any help.

best regards,

andrea :)
