They apparently bypassed the Denver area entirely, going through Wyoming, including Yellowstone, where they now are being feasted on by grizzly bears.

In the article, army cutworm moths = miller moths.

I can't speak for the rest of Colorado, though. For all I know, the plains, northern Colorado, etc. may have had miller sightings in normal numbers. I just have not seen any in the Denver area.
