Larva Identification Request - SE Texas

I second that. 

Wow! Thanks for that quick reply. Out of curiosity, do all long horn beetle larvae look similar and that is why you were able to identify the family but not the species? Is there any thing I can look for that would help pin it down?

I am clearing some land and have some cedars that I would like to keep but there are quite a few of these white things around and I am worried they might be invasive.

Thank you once again. After googling "cerambycid" I can see that it might be a bit naive to expect something specific. Now I am eager to see what it becomes.

Not many people raise cerambycidae, but you can. I'd take the piece that has the grub(s) and cut it into a manageable chunk and let it continue it's normal
life cycle, which depending on species could be a year or more. You could make a sleeve out of window screen, tie it around the chunk and wait.
There is a beetle forum where more people raise beetles, coincidentally, it's called-beetleforum.net.
Maybe someone there has better rearing information.
I remember chopping wood and finding very large pine sawyer grubs, they ended up bird food though.

I wasn't aware that the species had reached that far. Like most Anoplophora, it's a beautiful beetle; unfortunate that it also happens to be invasive.

I've read that as well, they're depicted in Mcmonigles's guide to rearing beetles.
