Many Thanks to "Home Guy" for the information on the Bark Beetle.
Sure sounds like what I have encountered! Will check out the tree
tomorrow for the symptoms listed. Won't help now since the tree is
dead, but may answer my question!

For those of you that don't know what kind of pine you have, this might
help:

You might have a spruce tree, not pine:

For those of you in Texas - I don't have to tell you that you've been
having a serious drout. Have you been watering your trees?

This product might help prevent future tree problems caused by bugs
(perhaps only crawling ones?)

I think the bottom line is that the bark beetle is attracted to trees
that are stressed potentially or perhaps most often because of a lack of
water.
