CLOSED: Bug ID please

Lewisville, TX(Zone 7b)

I saw this bug last year & wondered what is was..never seeing one before. Is it a beneficial one or not? Of course I haven't seen one like it since. Sorry for the poor quality, it was taken rather quickly.

That looks like the Cottonwood Borer (Plectrodera scalator): http://davesgarden.com/guides/bf/go/1351/

Most longicorn beetles have larvae that bore into wood of various trees. This species apparently is a borer of Cottonwoods. Not therefore beneficial, but I don't know if they are a serious pest,
