Butterflies

[Daniel & Monica Glaeske]

Dear Leps-lers

Just was reading in a book the other day about classification of the
Lepidoptera. Under a new scheme, Papilionoidea and Hesperioidea were
grouped together with an obscure family of moths, Hedylidae (?spelling).
I had never heard of this family before and know nothing of them.  Is
anyone familiar with this group, or why they are linked with
butterflies?

Regards, 

Daniel
