UPDATE: The NYT resists the appellation "rasberry":
Scientists do not quite know what to call them, they are so new. But folks in the damp coastal belt south of Houston have their own names (some of them printable) for the little invaders...Yeah, don't let some exterminator stick his name on these important ants — even if he does have a cool name. Speaking of having a name that's good for an ant, there's Paul Nester of Texas A&M University.
“We call them running ants,” said Diane Yeo, a homeowner...
The species, which bites but does not sting, was first identified here in 2002 by a Pearland exterminator, Tom Rasberry, who quickly lent his name to the find: the crazy rasberry ant.
“They’re the ant of all ants,” said Dr. Nester, who said they had infested five coastal counties, “and are moving about half a mile a year.”Oh, no! There the new killer bees — advancing on us!
