Natural Habitat

Found on the underside of leaves, stems, and flower buds of a wide variety of garden plants, crops, and trees.

Diet & Feeding

Herbivorous. Aphids use needle-like mouthparts to pierce plant tissue and suck out the nutrient-rich sap (phloem).

Behavior Patterns

They are known for rapid asexual reproduction (parthenogenesis). They often form large colonies and excrete a sticky substance called honeydew, which can attract ants and promote fungal growth.

Risks & Benefits

Risks: Major garden and agricultural pests that cause leaf curling, stunted growth, and can spread plant viruses. Benefits: They serve as a vital food source for beneficial insects like ladybugs, lacewings, and hoverflies.
