True,
C. lancifer has a deep metallic blue colour that's not very common in beetles. Here's another good
photo of a male. Another species,
C. ensifer, is just as large but is green instead of blue.
Males have more prominent sculpturing on the pronotum than the females, and usually have proportionately larger horns.
I've never heard of anyone breeding any species of
Coprophanaeus, but despite the extra effort which would undoubtedly be involved, they would certainly be a very interesting and worthwhile genus to work with, especially the larger species such as
lancifer and
ensifer. Incidentally, one small species,
C. pluto ranges into the southernmost point of TX. It's completely black in colour, and only the size of US
Phanaeus species.
