Predators are insects that hunt for their food, catching, killing, and eating a wide variety of other insects. Some types of predators, such as hover or syrphid flies, are predatory only as immatures or larvae, preying primarily on aphids, mealybugs, scale insects, and other soft-bodied insects.
Dragonflies - Adult dragonflies feed on insects such as mosquitoes, midges, flies, and winged ants.
Ladybugs - Larvae and adult ladybugs feed primarily on aphids, but they will also eat scales, caterpillar eggs, and mites. If left unchecked, aphids can stunt plant growth, deform and discolor leaves and fruit, or cause galls to form on leaves, stems, and roots.
Green Lacewings - Lacewing larvae, called “aphid lions,” are extremely carnivorous and prey on many soft-bodied insects and mites. They devour insect eggs, thrips, mealybugs, immature whiteflies, and small caterpillars. They can consume over 200 aphids or other prey in a single week.
Ground Beetles - One of the most striking ground beetles is the caterpillar hunter. This species is about an inch long and is a brilliant metallic green color. Both the larvae and adults eat other insects, while one group even feeds on snails.
