Description: Small wasps with narrow waists, long antennae, and ant-like heads, usually less than ½ inch (1.2cm) long, with a long black ovipositor extending from their rear ends. Black is the apparent color at first glance, but many species have orange or reddish abdomens. Braconid wasps do not sting.
Can Braconid Wasps sting you?
Braconid females can use the ovipositor, the tube through which eggs are laid, to sting. They generally don�t unless trapped or mishandled. The sting is considered medically harmless. The female wasp uses her ovipositor to lay eggs just under the skin of an unlucky hornworm.
What do parasitic wasps look like?

Are Braconid Wasps good?
Braconids are beneficial insects that lay their eggs inside or on host insects, and then the maggot-like wasp larvae weaken the host pest. Boost the braconid wasp population in your garden for natural control of caterpillars (including tomato hornworms), flies, leaf miners and aphids.What do Braconid wasp do?
Braconid wasps are Mother Nature’s way of keeping pests like hornworms under control. These parasitic wasps disrupt their host insect’s development, effectively stopping the pest in its tracks. Braconid wasps are parasitoids, meaning they eventually kill their hosts.
Where are Braconid Wasps found?
Braconid Wasps (Hymenoptera) North America is home to nearly 2,000 species of these non-stinging wasps, which are also found in Europe and other temperate climates. Adults are less than half an inch long, with narrow abdomens and long antennae.

Braconid wasps most well-known enemy, in terms of its prey, is the tomato hornworm caterpillar. Adult braconid wasps are highly attracted to the scent of caterpillars who munch on plants.
What is the symbiotic relationship between tomato hornworm and Braconid wasp?The braconid wasp is considered a parasitoid of the hornworm because it causes the hornworm to die as it pupates. By the time the wasps undergo metamorphosis, all of the hosts insides have been digested, thus by the time they are ready to pupate, the caterpillar will die.

Most adults have two sets of wings, although some may be wingless in the adult stage.
How long does it take for Braconid wasp to hatch?
Eventually the wasp larvae emerge and spin silk pupa cases (cocoons) on the skin of the dying hornworm caterpillar, inside of which they transform into winged adults within four to eight days.
How long does it take for parasitic wasps to hatch?
When they awaken in the spring, they start building new nests made of small cells, similar to a honeycomb. A queen lays one egg in each of the cells, and within 2 or 3 days, the eggs hatch.
What is the white stuff on Caterpillar?
Each white object you see on the caterpillar’s body is the cocoon of one of these wasps. A new generation of adult wasps will emerge from these cocoons to mate and lay eggs on the next crop of hornworms. To reduce the population of hornworms in your garden, leave the cocoon-carrying caterpillars alone.
How do I put parasitic wasps in my garden?
Make them at home: Adult parasitic wasps eat nectar and pollen. To attract them, plant umbrella-shaped flowers and herbs, such as yarrow, Queen Anne’s lace, zinnias, fennel and dill. These wasps also savor alyssum, cosmos, allium, statice and thyme.
What insect lays eggs on hornworms?
The white obtrusions are actually the cocoons of a parasitic wasp. A female wasp has laid her eggs under the skin of that hornworm. As the eggs hatch the larvae actually feed on the hornworm insides. The larvae eat their way out of the caterpillar and spin the cocoons you see.
Which wasp lays its eggs in caterpillars?
A female Glyptapanteles wasp pounces on a caterpillar, drilling into its flesh with what is known as an ovipositor (literally, “egg placer”), and pumps up to 80 eggs into its body cavity, according to Janssen.
What does the hornworm turn into?
Hornworm caterpillars turn into sphinx or hawk moths, a remarkable group of moths that often fly during both day and nighttime hours. With their sharp wings and hovering flight, hawk moths are frequently mistaken for small hummingbirds. Adult moths lay their large, spherical eggs on the undersides of leaves.

How can a ladybug be forced to guard a wasp parasite?
A parasitic wasp protects itself from predators while cocooned by turning its ladybird host into a “bodyguard”. After a female wasp injects its egg into the ladybird, the larva munches on its host’s internal tissues before breaking out through the abdomen.
