Look out Mothra.It’s not a scene from a cheesy Japanese science fiction flick, but swarms of pesky, messy miller moths have descended on the Golden Belt on their annual migration westward. Although harmless, “they can be a pretty big nuisance,” said Phil Sloderbeck, a Kansas State University Extension entomologist out of Garden City.“Miller” is a loosely used term generically applied to a number of different moth species.
