It is later than typical, but we finally detected the emergence of overwintering generation adults in SW MN on June 23. Apparently, our emergence cages missed the beginning of the emergence by a few days. While we did not notice any obvious symptoms, soybean stem dissections revealed some small white larvae. By June 27, we were starting to see a few 3rd instar larvae.
