Your letter to the bugman:  Was working the night shift and came across this gentle giant and was just wondering if it had a specific name?
Besides Moth?
How you want your letter signed:  Kindest Regards Ray

Dear Ray,
We believe this is a Wood Moth or Goat Moth from the family Cossidae, a group well represented on Butterfly House, but we would not discount that it might be a Ghost Moth or Swift Moth from the family Hepialidae, also well represented on Butterfly House.  We not only have trouble distinguishing the families apart, we also have problems with actual species identifications.  The larvae of Wood Moths are frequently called Witchetty Grubs. 

Hello,
Just wanted to take the time to say thank you for your reply!
It is greatly appreciated
Kindest Regards
Ray Davis
