Aphids, also known as plant lice, are small, soft-bodied insects that feed on the sap of plants. They are a common pest that can damage plants by sucking the juices from leaves, stems, and flowers, causing them to wilt and turn yellow.

Aphids can reproduce quickly, and a single female can produce hundreds of offspring in a matter of days. They are also known for their ability to transmit plant viruses, which can further damage plants.

There are many different species of aphids, each with their own preferred host plants. Some species of aphids have wings and can fly to new host plants, while others are wingless and crawl from plant to plant.

There are a variety of methods for controlling aphids, including natural predators such as ladybugs and lacewings, as well as insecticidal soaps and oils. Regularly inspecting plants for signs of aphid infestations and promptly addressing any problems can help to minimize damage to plants.
