the life of a corn earworm
The Life of a Corn Earworm

The life of a corn earworm starts with an egg.

The female adult moth smells the silk of a corn. Moths can smell corn silk from miles away.
The moth flies toward the corn to lay her eggs. When the eggs hatch, they will find food and shelter inside the corn ear.

The larvae follow the silk channel to the tip of the developing ear where they feed on kernels and grow.

  • The worms come in a variety of colors: green, tan, brown, pink, maroon, or nearly black.

It took 21 days for our corn earworms to start metamorphosis.


Is the moth a male or female?

Hold the moth and gently squeeze the abdomen. The females will have a brownish small part pop out. They are usually less active and have shorter, fatter abdomens than the males. Females are usually darker.
