There are native elm bark beetles and northern corn rootworms, both of which start with the letter “N.” Another insect that starts with the letter is the netwinged beetle.
Elm trees all over Minnesota are home to native elm bark beetles. The beetles are small. When fully grown, they rarely get bigger than an eighth of an inch. The beetles lay their eggs in the elm trees, which they take over. Under the bark, you can find the eggs. This action leads to Dutch Elm disease, which is a fatal disease that has led to fewer of these trees.
All over the world, the northern corn rootworm can be found on corn plants. The bugs don’t get much bigger than three-sixteenths of an inch, and they are most common in the Midwest of the United States. When the rootworm lays eggs, the corn stalks become food for the eggs.
The netwinged beetle lives from Wyoming in the west to Canada in the north. This bug lays its eggs on plants that are dying.
