Luna Moth

[Tightman]

My daughter Megan is in second grade at Cornwall Terrace Elementary School
in Sinking Spring, PA (one hour from Philadelphia).  She is studying
insects during this quarter and she chose the Luna Moth to research.  I
have found very little data on the Luna Moth on the internet (mostly
pictures).

What purpose does the Luna Moth serve?  What, if any, benefits does it
offer the ecology?  Is there a site on the Web that I can gather data like
this?

Any help would be appreciated.  Thank you for your time.  My name is Tony
