Asparagus beetles have a similar look to lady bugs. As larvae, they are 1/3 inch long and are slug like in appearance. Adult asparagus beetles are about 1/4 inch in length and are metallic blue-black with either yellow or black spots on their wings. Both adult and larvae can be dangerous to your asparagus causing the tips to turn brown and twist.
The adult onion fly resembles the house fly, but smaller. The larvae are legless and creamy-white and will cause the plants to wilt and die.
Corn earworms (also known as tomato fruitworms) are small caterpillars that vary in color from different shades of brown, yellow, pink, green, and black. The light yellow adult moth lays white, circular eggs on leaves or corn silk in the spring time. The earworm consumes the silk and then moves on to the ear. On other plants, earworms consume stems, leaves, and fruit.
Tomato hornworms are huge caterpillars that are green with a spiky tail and orange spots on the abdomen. These giants are monsterous and can destroy a tomato plant in the course of a day, so it is important to catch them fast!
