Milkweed Longhorn - Tetraopes femoratus

Milkweed Longhorn - Tetraopes femoratus
Victoria, Victoria County, Texas, USA
September 16, 2012
I found it on Asclepias oenotheroides.
Very similar with Tetraopes texanus.
What make me to suppose to be Tetraopes thermophilus it is the fact that the first segment of antenna is black not red.
I used the picture find on BG to ID.
I have several similar photos. Unfortunately I did not have the proper lens to the camera and the focus is poor.

Dan Heffern says:
"This is one case where specimen really needs to be collected and put into an institutional collection if you want a name.
"I could call this T. thermophilus and probably nobody would raise an eyebrow. However, in some cases I will not give a name to a photographed specimen, and this is one of those cases. T. femoratus and T. thermophilus are similar and I have had trouble identifying pinned specimens. I have not seen a lot late season Tetraopes from Texas even in the Texas A&M collection.
"Some Texas Tetraopes are May- and June-active, but T. femoratus and T. thermophilus are presumably late summer or fall. So let's not try going any further."
