At my house, I leave existing desmodium, I've even brought in types that I didn't have. Very attractive flowers, and quails and doves are said to eat the seeds.
The long tailed skipper will make do with your patch of climbing beans...
or even centrosema...
You didn't mention coffee weed!
As legumes, both coffee weed and desmodium should improve the soil while raising butterfly families.
As locally native plants... both should be there already.
When I mention growing Croton capitatum for the leafwings... I've had texas people complain about this native plant's supposed invasiveness... I haven't seen any invasive qualities in the 5 or 6 years I've been growing it.
As the leafwing butterfly has been difficult to capture by camera, link to butterflies and moths dot org:
