Bug found on mesquite trees in S. Texas -
Placosternus erythropus
-
Loyola Beach, Kleberg County, Texas, USA

Size: 3/4"-1"
Discovered after a limb in a mesquite tree fell down. Very pretty black and yellow. Maybe some type of borer?

Male & female?
I hope I'm not too presumptuous in labeling these male and female.

Not so fast:-)
I agree that these are longhorned beetles in the genus Megacyllene, but maybe not locust borers. There are several very similar species in that genus.

Another possibility
Mike Quinn (Texas state entomologist) has identified a common south Texas species as Placosternus difficilis, with the English name Mesquite Borer.

I'm about to post a couple of images I took recently. Could DD's beetles be this species, rather than Megacyllene? (assuming one genus isn't a recent split from the other...)

Numerous spp.
As mentioned, there are several spp. in TX - the only one I couldn't rule out (based on typical examples seen) was M. comanchei Rice & Morris, 1992:200 - haven't seen, but many of these are quite variable.
