Many insects are predators of aphids. Most plants do not like aphids because they sap the plant’s nutrients. Aphid predators help keep the population of aphids in check by feeding on the aphids, causing a decrease in their population.
The main predator is ladybugs that eat and kill the entire colony of aphids. Ladybugs are small insects that have a round shape with dark spots on it and red eyes. Ladybug eggs are usually laid on leaves or stems where they hatch into larvae which then feed on the aphid eggs, one by one, until they are all gone.
Ladybugs can also be preyed upon by many other predators like parasitic wasps, praying mantis, lacewings and green lacewings as well as vertebrate predators like frogs.
