Many of you will be walking your fields during the next couple of weeks inspecting corn emergence, determining plant population, and maybe scouting for black cutworm injury. During the month of May, it is not uncommon to find a variety of insects in the field, but not all of them will be pests. I was digging for white grubs in Ringgold County (south-central Iowa) on May 10 and uncovered several species of insects. Because all of these insects will occur across the state, I wanted to help you correctly identify them in case you also encountered them.
