According to Colorado State University Extension, we can breathe a sigh of relief that miller moths will be substantially less in numbers this year. How happy does this make you?!?
CSU says "nuisance problems with migrating army cutworm moths in eastern Colorado will be substantially less than in the previous year and will occur later. Unlike in 2020, when there were numerous reported outbreaks of army cutworm caterpillars in eastern Colorado, western Kansas and Nebraska, numbers of cutworms in Spring 2021 seem to be in much lower numbers..."
The article goes on to state "good spring moisture conditions present in much of the state, and much better relative to 2020, should promote many more sources of blossoming flowers, which are the source of nectar that the moths seek during their annual Plains-to-Mountain spring migration.
With more abundant blossom availability moths do not concentrate so heavily in irrigated landscapes, and become less noticeable.
Miller moth season is expected to peak in early-mid June but could be noticeable well into late June.
