Rough stink bugs feed primarily on leaves and developing seeds of trees and have been recorded from ash, walnut, willow, boxelder and many other species. However, they do not appear to be associated with any significant plant injuries. In addition,
they are occasional predators and have been found feeding on caterpillars and leaf beetle larvae. For more info on Rough Stinkbugs in CO, see the CSU website webdoc.agsci.colostate.edu/bspm/Hexapoda%20%28Insects%29/...
