Photo of a fall armyworm, distinguished from the true armyworm by the upside-down, cream-colored “Y” shape on its head capsule. Fall and true armyworms are actually “immatures” or caterpillars of moths. In large numbers, these insects can be devastating to hayfields and pastures due to their appetite for green grass crops. Recent increases in these two species in Central Texas have created some problems for producers. (Texas Cooperative Extension photo by Dr. Bart Drees)
