Salo, C. 2023. Letter to the Editor: More Reasons to Appreciate the Miller Moth. Colorado Times Recorder, July 19.
Although High Country News declined to publish my letter correcting the misinformation in their miller moth piece, the Colorado Times Recorder (which republished HCN’s piece) did.

What is cheatgrass and why is it a problem in the West? What do we know about army cutworms and cheatgrass and how well accepted is this knowledge? And what do bears have to do with army cutworms and cheatgrass?
Salo, C. 2021. To predict cheatgrass die-offs we must understand their cause. Sage Science blog, May 19. Two recent federal reports overlook army cutworms as a likely cause of cheatgrass die-offs. The cause suggested by the reports has not been clearly linked to die-offs and is a more complex and less direct explanation for these episodic events.

Predicting die-offs might be easier than predicting reseeding success: look for big late summer rains, lots of miller moths in fall, then dry weather through January.
Salo, C. 2018. Army cutworm outbreak produced cheatgrass “die-offs” and defoliated shrubs in southwest Idaho, 2014. Rangelands 40(4):99-105.
This study predicted an army cutworm outbreak and monitored vegetation damage and subsequent recovery at four sites. These outbreaks seem to occur during extended drought, when late summer rains germinate winter annuals for the larvae to eat, and dry winter weather allows many larvae to survive. I also outline a simple method for identifying die-offs to prioritize them for reseeding with desirable species.

Conditions similar to those before the 2003 army cutworm outbreak and cheatgrass die-offs occurred in southwest Idaho in 2014. The large numbers of larvae ate winter annuals and shrub foliage in low, dry areas of the Snake River Plain of Idaho to produce cheatgrass die-offs.
