From Wikipedia: The soldier beetles are relatively soft-bodied, straight-sided beetles, related to the Lampyridae or firefly family, but unable to produce light. They are cosmopolitan in distribution. One of the first described species has a color pattern reminiscent of the red coats of early British soldiers, hence the common name. They are also known commonly as leatherwings because of their soft elytra.
Cantharidae are all predaceous. It is likely that these beetles help by feeding on maize insects and their eggs. But they also feed on pollen - the large quantities shed by the maize tassles are a food source. The immature larvae should be searched for among decomposing leaves and stalks of maize following harvest.
