A lacewing is an insect belonging to the family Chrysopidae, known for its delicate, lacy wings. These insects are typically green or brown and are often found in gardens and forests. Lacewings are beneficial to agriculture as their larvae feed on pests like aphids and mites, helping to control these populations naturally. Adult lacewings are attracted to light and are often seen flying around at night. They lay their eggs on plants, and when the larvae hatch, they begin to hunt for food. The presence of lacewings can indicate a healthy ecosystem, as they thrive in environments with abundant plant life and minimal pesticide use.
