Hyalophora specimens from southern Arizona often possess characters that are seemingly more congruent with euryalus than with gloveri or often very intermediate between the two (gloveri x euryalus). There has been speculation, these moths may in fact be part of a cline involving a greater species complex composed of columbia, gloveri and euryalus.

NOTE: The individual above is similar in size and appearance to lab produced hybrids (gloveri x euryalus) as seen below.


--------------------------

As mentioned above, many of the gloveri in s. Arizona seem to possess traits seen in both gloveri & euryalus (color and pattern).

The size and shape of the crescents are particularly variable!
