| Ostrinia nubilalis (Hübner, 1796) |
The European Corn Borer, Ostrinia nubilalis is a pest of maize, and is native to Europe although it is found in North America as well. Female corn borer moths lay clusters of eggs on corn leaves, usually on the underside of the leaf.
The egg masses, or clusters, are laid in an overlapping configuration and are whitish-yellow in color. As the larvae develop inside their eggs, the eggs become more and more transparent and the immature caterpillar's black head is eventually visible. The caterpillars hatch by chewing their way out of the eggs.
European corn borer caterpillars damage corn plants by chewing tunnels through the corn stalks and ears.
Biological control agents of corn borers include the hymenopteran parasitoid Trichogramma.
