Aphids are also known as plant lice. Aphids are tiny pear-shaped insects with long legs and antennae. Depending on the species and the plants they feed on aphids range from green, yellow, brown, red, or black.
Aphids are a top garden pest and are most active in the spring and decrease with the rise in hot summer temperatures. Aphids are slow moving and live on the plants they feed on, causing noticeable damage to the plant.
