A very hungry caterpillar problem
Some parts of Africa are being affected by a pest known as the "fall armyworm".
But it's not a worm, despite its name. It's actually a hungry caterpillar that is eating crops.
It's a big problem for farmers because it is eating maize and other crops, which people depend on for food.
What's making it worse, is that it is a new pest, so farmers and the government don't know how to get rid of it.
