Aphids are small, soft-bodied insects that feed on plant sap. They are typically found on the stems, leaves, and flowers of plants and can be green, yellow, white, or black in color, depending on the species and the plant they're feeding on. Aphids are usually between 1-10 mm in length, and they have a distinctive pair of cornicles, or tailpipes, at the rear of their body.

Identifying aphid infestations early on is crucial to prevent the spread of the pests and minimize damage to your plants. Some common signs of aphid infestation include:

• Curled or distorted leaves
• White, cottony residue on the leaves or stems (aphid honeydew)
• Actual aphids on the plant, often found on the undersides of leaves or on the stems
• Ants or other insects attracted to the honeydew
• Reduced plant growth or stunted leaves
