Aphid

Found on a wide variety of plants, including garden plants, crops, and ornamental plants. They tend to cluster on new growth, undersides of leaves, and young stems.

Aphids are sap-feeders. They use their piercing-sucking mouthparts to extract nutrient-rich sap from plants. This can lead to stunted growth, distorted leaves, and reduced plant vigor.

Aphids often reproduce rapidly through parthenogenesis (asexual reproduction), leading to large colonies. They can be wingless or winged; winged forms develop when colonies become overcrowded or plant quality declines, allowing them to disperse to new host plants. They produce a sticky, sugary waste product called honeydew, which can lead to sooty mold growth.

Risks: Major agricultural pests, causing damage to crops and garden plants, and transmitting plant viruses. Benefits: Serve as a food source for many beneficial insects (e.g., ladybugs, lacewings) and birds, playing a role in food webs.
