Soldier beetles can be common in Iowa crops, especially corn and alfalfa, but they do not feed on either of these crops or soybeans. These beetles are known as leather wings in some regions of the U.S. and they somewhat resemble lightning bugs or fireflies, but they lack the light-producing organ on the abdomen and the head is not tucked under the pronotum.
