Southwestern Corn Borer
A pale moth whose larvae bore into corn stalks and girdle stems from the inside, causing extensive lodging. It is a major corn pest in the southern Great Plains of the United States.
Did You Know?
Overwintering larvae girdle the corn stalk from the inside, deliberately weakening it so the stalk falls and provides insulated shelter.
Fan-foot Moth
A subtle brown moth with fan-shaped palps and delicate wing markings. Found in woodland where dead leaves accumulate. Larvae feed on dead leaves on the woodland floor.
Did You Know?
The males have distinctive enlarged fan-shaped labial palps that give this moth its common name.
