What are Lace Bugs?

Lace bugs are a type of insect that belongs to the family Tingidae. They are named for the delicate, lacy appearance of their wings and body, covered in a complex pattern of veins and ridges.

Host Plants

There are many different species of lace bugs, but some of the most common ones that affect garden plants include the azalea lace bug, the sycamore lace bug, and the hawthorn lace bug. These bugs can also infest ornamental plants such as rhododendrons, mountain laurel, and flowering dogwood.

Regions impacted

Lace bugs are found throughout the world in a variety of different habitats but are most commonly found in temperate and tropical regions.


Adult lace bugs typically range in size from 1/8 to 1/4 inch (3-6 mm) long and may be a variety of colors, including brown, black, gray, and green. They have a flattened, oval-shaped body with distinctive wings that are held flat over the body when at rest.

Life Cycle

The life cycle of lace bugs generally consists of four stages: egg, nymph, pupa, and adult.

  • Egg stage: Female lay their eggs on the undersides of leaves, typically in groups. The eggs are small, oval-shaped, and often covered in a sticky substance that helps them adhere to the leaf surface.
  • Nymph stage: Once the eggs hatch, the young bugs emerge as tiny, wingless nymphs. Nymphs go through several stages of development, during which they molt and gradually grow in size. Nymphs typically feed on the sap of plants, causing discoloration and damage to the leaves.
  • Pupa stage: As the nymphs approach adulthood, they develop a hard, protective covering called a pupal case. The pupal case is often anchored to the leaf surface by a network of silk threads and provides a safe environment for the developing insect.
  • Adult stage: Once the pupal stage is complete, the adult emerges from the pupal case. Adults have wings and are fully capable of flight, allowing them to disperse and colonize new plant hosts. Females are able to lay eggs and begin the life cycle anew.

The length of the life cycle can vary depending on the species and environmental conditions. In general, however, the life cycle from egg to adult can take several weeks to several months to complete.

Damage and Detection

Lace bugs can cause a range of damage to plants, including stippling, yellowing, and wilting of leaves, as well as stunted growth and reduced vigor. The damage is typically most severe on the undersides of leaves, where the insects feed and lay their eggs.

One of the key signs of lace bug damage is the presence of small, black fecal droplets on the undersides of leaves. These droplets are a result of the insect’s feeding behavior and can often be used to identify an infestation. In addition, affected leaves may exhibit a characteristic stippling pattern, with small white or yellow spots where the insect has punctured the leaf tissue to feed.

Lace bugs can be difficult to detect, as they are relatively small and may blend in with the plant material. However, careful observation of the undersides of leaves can often reveal the presence of the insects or their eggs. Additionally, if the damage to the plant is severe, it may be possible to spot the insects crawling on the leaves or flying near the plant.

If left untreated, lace bug infestations can lead to significant damage to plants, including reduced growth, defoliation, and even death in severe cases. As such, it is important to monitor plants regularly for signs of lace bug damage and to take action if an infestation is detected.

Prevention and Control

Preventing and controlling lace bugs can involve a combination of cultural, mechanical, and chemical methods. Here are some strategies that can be effective:

  • Monitor plants regularly: Regular inspection of plants can help identify infestations early before they have a chance to spread.
  • Remove infested leaves: Prune away and discard heavily infested leaves to help reduce the number of lace bugs on the plant. Be sure to dispose of the leaves carefully, as they may still contain eggs or nymphs.
  • Use a high-pressure water spray: using a high-pressure water spray can be an effective method for controlling lace bugs on plants.
  • Increase plant vigor: Providing plants with adequate water, nutrients, and light can help them grow more vigorously, making them better able to resist lace bug damage.
  • Apply insecticidal soap or horticultural oil: These organic pesticides can be effective if applied regularly and thoroughly to the undersides of leaves.
  • Apply systemic insecticides: These chemicals are absorbed by the plant and can provide longer-lasting protection against lace bugs, but should be used with caution and according to the product label.
  • Use beneficial insects: Ladybugs, lacewings, and other predatory insects can help control lace bug populations naturally. Consider introducing these beneficial insects to the garden or providing habitat and resources to encourage them to move in on their own.

Overall, preventing and controlling lace bugs requires a multi-faceted approach that takes into account the specific needs and characteristics of the affected plant and environment. By using a combination of cultural, mechanical, and chemical methods, it is often possible to reduce their damage and protect plants from infestation.
