Saw this one my front step and removed it to where it climbed a cardon cactus.
Wondering if you could tell me what it is?

Elephant Beetle

Dear Karin,
We are not used to seeing Rhinoceros Beetles in the subfamily Dynastinae that are so hairy, but we located this BugGuide image of an Elephant Beetle that looks quite similar to your individual.  According to BugGuide:  “7 spp. of
Megasoma occur in the southwestern United States and Northern Mexico, only one of which occurs in Texas.”  We are confident the genus Megasoma is correct, but we cannot say for certain which species you encountered.  Here is a FlickR image of Megasoma theristes.

Thank you for your prompt reply. Having looked at  FlickR image of Megasoma theristes,  
I am quite confident that it is very close to this one, especially since the location this one was photographed in is very close to Todos Santos, BCS, Mexico.
Karin
