Braconid Wasp

Family Braconidae

Braconid Wasps are valuable and versatile insects used in agriculture and horticulture to control pests. They are also important pollinators. They feed on nectar and other sweet substances, and in the process, they transfer pollen between flowers. This helps to fertilize plants and is essential for maintaining healthy ecosystems.

Where to find them

Braconid Wasps are found in various environments, including forests, fields, gardens, and urban areas. They are widely distributed worldwide, with species present in most regions, including North America, Europe, Asia, and Australia.


The Braconid Wasp is a small to medium-sized insect that belongs to the family Braconidae. They typically measure between 1/32 inch (1 mm) and 3/8 inch (10 mm) in length, with a slender body and delicate, translucent wings. They can be black or brown in color, with some species displaying markings or stripes of other colors.

Life Cycle

The life cycle of a Braconid Wasp typically consists of four stages: egg, larva, pupa, and adult.

  1. Egg: The female Braconid Wasp lays eggs on or inside the body of a host insect, such as a caterpillar, aphid, or beetle larva.

  2. Larva: Once the eggs hatch, the wasp larvae feed on the host insect. They burrow into the host's body, feeding on its internal tissues. The larvae grow and molt several times, eventually reaching full size.

  3. Pupa: After reaching full size, the larvae form a pupa, a resting stage in the life cycle. During this stage, the larvae transform into adult wasps.

  4. Adult: The adult Braconid Wasp emerges from the pupa, fully developed and ready to mate and lay eggs. Female wasps will seek out new host insects on which to lay their eggs, and the cycle begins again.

The length of the life cycle can vary depending on factors such as temperature and the availability of host insects. However, in general, the entire life cycle from egg to adult can take anywhere from a few weeks to several months.

Why a Beneficial Insect?

Braconid Wasps are considered beneficial for several reasons:

  1. Biological control agents: Braconid Wasps are known for their parasitic behavior, where they lay their eggs on or inside the bodies of other insects, such as caterpillars, aphids, and beetle larvae. The wasp larvae feed on the host insects, eventually killing them. This makes Braconid Wasps important biological control agents for many agricultural pests, as they help to reduce the populations of harmful insects that can damage crops.

  2. Pollinators: In addition to their role as parasites, Braconid Wasps are also important pollinators. They feed on nectar and other sweet substances, and in the process, they transfer pollen between flowers. This helps to fertilize plants and is essential for maintaining healthy ecosystems.

  3. Low-impact control: Unlike some chemical pesticides, Braconid Wasps are a low-impact way of controlling pests. They do not harm beneficial insects, and they are not toxic to humans or pets.

  4. Ecological balance: By controlling pest populations, Braconid Wasps help to maintain a natural balance in ecosystems. This, in turn, helps to ensure the health and stability of the plants and animals that rely on these ecosystems for their survival.

Overall, Braconid Wasps are considered important and beneficial insects, playing a crucial role in maintaining healthy ecosystems and controlling harmful pests.

Attract this Beneficial Insect to your Garden

To attract Braconid Wasps to your garden, you can try the following tips:

  1. Plant native flowers: Braconid Wasps feed on nectar and other sweet substances, so planting native flowers that bloom at different times of the year can provide a consistent source of food for them.

  2. Create a habitat: Braconid Wasps need a place to lay their eggs, so consider providing them with a suitable habitat, such as a butterfly or insect house. You can also create habitat by leaving piles of leaves, twigs, or grass clippings in the corner of your garden.

  3. Avoid pesticides: Chemical pesticides can harm Braconid Wasps, so try to avoid using them in your garden. Instead, consider using low-impact pest control methods, such as companion planting, hand-picking pests, and releasing beneficial insects.

  4. Provide water: Braconid Wasps, like all insects, need water to survive. Provide them with a shallow water dish, or consider installing a bird bath or fountain to attract them.

  5. Reduce mowing frequency: Braconid Wasps often use long grass as a place to lay their eggs, so reducing the frequency of mowing can help to attract them to your garden.

By following these tips, you can create a garden that is friendly to Braconid Wasps and other beneficial insects, helping to maintain a healthy and diverse ecosystem in your yard.
