Up in ND, they're concentrated in the beans and sugar beats. I'm seeing more in the beets right now, but some in the beans and alfalfa as well. Come the first frost, they'll move into sunflowers, corn and more of the alfalfa. Come opener of rifle season when everyone stirs them up, they'll stay in the unharvested corn and sunflowers to never be heard of again..... (In case you missed it, I'm not a huge fan of ND having their rifle season during the rut).
