Are these both six-spotted milkweed bugs? There seems to be a color difference. Variations of the same species? Please advise.

Oncopeltus guttaloides
According to Slater, 1964,
O. sexmaculatus
do occurs in TX, but is missing from AZ, while
O. guttaloides
was originally described from this country.
Please notice the different habitus from the ones from TX, with a more slender shape, and the red femorae.
Though current keys are unclear on this point, it is very unlikely to be
O. sexmaculatus
wich is known only from East states where it has a different habitus while there is already
O. guttaloides
. I think this is
O. guttaloides rather
.
While
O. sexmaculatus
is described with black legs only, I came to thinking that in AZ
O. guttaloides
is far more variable, with dark, black-legged individuals, and lighter, red-legged ones.
I think your picture is figuring this diversity and that both are
O. guttaloides
.
