Corn Flea Beetle

A very small, shiny black to bronze flea beetle with a compact, oval body. It vectors Stewart's wilt bacterium, making it both a direct and indirect pest of sweet corn.

💡

Did You Know?

The severity of Stewart's wilt in a given year can be predicted by winter temperatures, since cold winters reduce overwintering beetle populations.

Sheep Ked

A completely wingless, tick-like blood-sucking fly that lives permanently in sheep wool. Its flattened body and strong claws allow it to cling firmly to wool fibers.

💡

Did You Know?

Despite being called a ked or tick, it is actually a true fly that has completely lost its wings through evolution.
