NOT a Christmas Beetle with Christmas Lights

Dear Jackie,
This is some species of Scarab Beetle in the family Scarabaeidae, but we cannot say for certain which species.  It reminds us of a female Rhinoceros Beetle in the subfamily Dynastinae.  One possibility might be a female
Megasoma nogueirae which is pictured on The Generic Guide to New World Scarab Beetles.  We love your photo with the Christmas Lights.  There is a group of Australian Scarabs which put in their yearly appearance around the holidays (Southern Hemisphere summer) that are known as Christmas Beetles.  While we fully realize your individual is not a Christmas Beetle, we were nonetheless reminded that we will most likely begin getting photos of that group from down under in the near future.
