Natural Habitat

Gardens, farms, and forests, typically found on the undersides of leaves or on new plant growth.

Diet & Feeding

Herbivorous; they use piercing-sucking mouthparts to feed on plant sap (phloem).

Behavior Patterns

Aphids are often found in large colonies and are known for their ability to reproduce rapidly via parthenogenesis (asexual reproduction). They excrete a sticky substance called honeydew which can attract ants.

Risks & Benefits

They are major agricultural pests that cause leaf curling, stunted growth, and can transmit plant viruses. However, they are a vital food source for beneficial insects like ladybugs and lacewings.
