TX Indigos aren't all that uncommon in good habitat in the southern parts of TX. Fortunately, much of that land is used for cattle (rather than crops or homes) and so is "less" screwed up than other areas. Along the lower parts of the Rio Grande Valley, the natural riparian woodlands along the river have been largely wiped out, except for a handful of preserves/NWRs along the river. I imagine Indigos will survive in S. Texas as long as they are protected and habitat protection continues in the patches that exist now. Unfortunately, TX Indigos are largely restricted to areas around water in SoTex, and those are the areas that are most conducive to agricultural destruction as well.
The taxon also ranges south into mexico quite a ways, but there the habitat destruction is extensive. It is quite uncommon to find errebennus in north eastern Mexico anymore. In over 15 years of birding/herping there, I have seen two. One AOR neonate in 1984 and a DOR big adult this year.
The Eastern is in much more dire straits mostly due to the rapid rate of habitat loss in Florida (thanks Mickey!) and the fact the current species range is very small compared to erebennus.
