Black cutworm adults (moths) were caught in pheromone traps across Iowa throughout much of April. Two major flights occurred in mid-April: the first during the nights of April 15 and 16 and the second four nights later. Moths were captured across Iowa during both flight events. Remember that having moth flights does not mean that a given field or area will have damaging black cutworm populations. From these observations, the likely first cutting dates can be projected for seedling corn across Iowa.
