Project Description

Flying Insects that Sting!


Hornets are among the largest of the social kind of wasps with their size reaching up to 45 mm in length.


A Hornet’s Life

The nest is established in spring time by a fertilized queen. The nest is created in sheltered places like dark hollow tree trunks. The queen hornet will build an initial nest of up to 50 cells. This is made by utilizing chewed up tree bark. One egg will be laid in each cell. The eggs hatch in 5 to 8 days. The larvae will develop through five instars for two weeks.

It is in these 2 weeks that the queen would feeds the larvae with insects. At the end of this period the larvae would come out of the cell as an adult having eaten its way out of the silk cap on the cell. This first generation of workers is mostly comprised of females. These worker hornets will now forage, build nest and take care of larvae. Only queen lays the eggs.

The population keeps growing. New layers of the combs are added and the nest grows. By late summer the colony could number up to 650 workers.

By the time the nest has matured, the queen starts to produce the first reproductive individuals. Fertilized eggs develop into females an unfertilized ones into males. The adult males do not forage or take care of the nest. In fall season the male leave the nest and mate during nuptial flights and die shortly after mating. The workers and queens survive at most until mid to late fall. And only the fertilized queens survive over winter.


Workers themselves feed primarily on carbohydrate-rich fluids such as tree sap. They also hunt other insects such as flies, dragonflies and smaller wasps and bees. After killing their prey all nutrient-poor parts such as the wings, legs, and head may be discarded but the thorax with the protein-rich flight muscles is delivered to the larvae. To keep the nest from over heating the workers will bring water to the nest and deposit it on the envelope.

Nest Responsibilities

This mostly constitutes building new cells and comb layers. And feeding the larvae with masticated prey flesh.


A hornet’s sting is painful to humans, but the sting toxicity varies greatly by hornet species. Some deliver just a typical insect sting, while others are among the most venomous known insects. Allergic reactions, fatal in severe cases, can occur in individual suffering from anaphylactic shock may die unless treated immediately via epinephrine (“adrenaline”) injection using a device such as an EpiPen, with prompt follow up treatment in a hospital.

Hornet Defense Alarm

Like most social wasps, Hornet can mobilize the entire nest for defense. This can be highly dangerous to humans and animals. The hornet alarm pheromone tells all that the nest is under attack. Same pheromone is used to indicate prey as well such as bees.

What not to do ?

  • Producing vibrations and loud noises near a nest.
  • Being within proximity of few meters of a nest.
  • Disturbing or killing a hornet within a few meters of a nest.
  • Blocking the path of a hornet.
  • Breathing onto the hornet itself or the nest.
  • Cause Rapid air movements
