Damsel Bug

Family Nabidae

Damsel bugs, also called Nabids, are beneficial insects that feed on garden pests such as aphids, leafhoppers, moth eggs, and small caterpillars. Damsel bugs are important for their ability to control pests that can damage crops and gardens. As a result, they are often considered beneficial insects and are a key part of integrated pest management programs.

Where to find them

Damsel bugs can be found worldwide and throughout North America in various habitats, including gardens, agricultural crops, and natural areas such as fields, meadows, and forests. 


They have a characteristic long and slender appearance, with a body that is typically brown or gray in color. They have large, compound eyes, long antennae, and a beak-like mouth that is used to capture and feed on their prey. Adult damsel bugs range in size from 3/16 to 19/32 inches in length (5 to 15 mm) and have flattened oval-shaped bodies. Some species have distinctive markings or patterns on their wings and bodies. They are active predators and move quickly to capture their prey.

Life Cycle

The life cycle of damsel bugs typically consists of four stages: egg, nymph, adult, and egg again. The length of the life cycle can vary depending on the species and environmental conditions but typically lasts several weeks to a few months.

  1. Egg stage: Female damsel bugs lay their eggs on leaves or stems near their prey. The eggs are small and oval-shaped and can be green, yellow, or brown in color.

  2. Nymph stage: Once the eggs hatch, the nymphs emerge and feed on small insects and other arthropods. They molt several times as they grow, gradually changing in appearance until they reach adulthood.

  3. Adult stage: Adult damsel bugs feed on larger insects and mate and lay eggs to complete the cycle. They are active predators and can be found on flowers, plants, and in the soil in search of prey.

  4. Egg stage: The cycle repeats as the newly laid eggs hatch and begin the nymph stage. Over the course of several generations, the damsel bug population can increase and help control pest populations in the area.

Why a Beneficial Insect?

Damsel bugs are considered beneficial insects because of their predatory behavior. They feed on many garden pests, including aphids, leafhoppers, moth eggs, and small caterpillars, such as corn earworm, European corn borer, imported cabbageworm, and armyworm, which can damage crops and gardens.

By controlling pest populations, damsel bugs play an important role in reducing the need for chemical insecticides and can help maintain a healthy balance of insects in the ecosystem.

In addition to their predatory behavior, damsel bugs are also beneficial because they do not cause any harm to humans, pets, or other non-target species. They do not bite, sting, or carry any diseases, making them a safe and natural option for pest control.

Attract this Beneficial Insect to your Garden

Damsel bugs can be attracted to your garden or crop by providing the right conditions and food sources. Here are some ways to attract damsel bugs to your area:

  1. Plant a variety of flowering plants: Damsel bugs are attracted to flowers for their nectar and pollen, and planting a diverse mix of flowering plants can help increase the population of these beneficial insects in your area. Damsel bugs like tall grasses to hide in, fennel, mint, goldenrod, and caraway plants.

  2. Provide shelter: Damsel bugs need places to hide from predators and extreme weather conditions. Providing shelter in the form of dense vegetation, mulch, or a bug hotel can help attract and retain damsel bugs in your garden.

  3. Reduce pesticide use: Pesticides can kill damsel bugs and other beneficial insects, so reducing the use of these chemicals can help maintain a healthy population of these insects in your area.

  4. Provide food: Damsel bugs feed on various garden pests. By providing a reliable food source, you can encourage damsel bugs to stay and breed in your area.

  5. Create a habitat: Creating a habitat that is attractive to damsel bugs can help increase their population in your area. This may include planting native wildflowers, providing cover in the form of rocks and wood, and using minimal tillage in your garden or field.
