I was in January 2013 in Costa Rica and saw a lot of bugs.
I search the net and bought some books but still didn’t find all the names.
Maybe you can help me with the determination of a few species.
This Arctiidae spec I found in Monteverde, january 2013 Costa Rica

This is not an Arctiid, but rather a Saturniid or Giant Silkmoth.  We visited The World’s Largest Saturniidae Site and we believe it is Dirphia horcana.  You may view a mounted specimen on Lepidoptera Pro.  We will try to contact Bill Oehlke for confirmation.

It is a Dirphia horcana female.
Dirphia subhorca females have brown lower wings while female horcana have orange underwings.
I would like permission to post this one so can you give me contact info. Very nice photo
Thanks ,
