'') build their nests underground or in other cavities. In the tropics, these nests may last year-round, but in temperate areas, the nest dies over the winter, with lone queens hibernating in leaf litter or other insulative material until the spring. Male hornets are docile and do not have stingers.
Hornets are often considered pests, as they aggressively guard their nesting sites when threatened and their stings can be more dangerous than those of
bees.

Some other large wasps are sometimes referred to as hornets, most notably the
bald-faced hornet (''Dolichovespula maculata'') found in North America. It is set apart by its black and ivory coloration. The name "hornet" is used for this species primarily because of its habit of making aerial nests (similar to some of the true hornets) rather than subterranean nests. Another example is the

Life cycle
In '' V. crabro'', the nest is founded in spring by a fertilized female known as the queen. She generally selects sheltered places such as dark, hollow tree trunks. She first builds a series of cells (up to 50) out of chewed tree bark. The cells are arranged in horizontal layers named combs, each cell being vertical and closed at the top. An egg is then laid in each cell. After 5–8 days, the egg hatches. Over the following two weeks, the larva progresses through five stages of development. During this time, the queen feeds it a protein-rich diet of insects. Then, the larva spins a silk cap over the cell's opening, and during the next two weeks, transforms into an adult, a process called metamorphosis
Metamorphosis is a biological process by which an animal physically develops including birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation. Some inse ...

, etc.) with the exception of egg-laying, which remains exclusive to the queen.
As the colony size grows, new combs are added, and an envelope is built around the cell layers until the nest is entirely covered, with the exception of an entry hole. To be able to build cells in total darkness, they apparently use gravity to aid them. At the peak of its population, which occurs in late summer, the colony can reach a size of 700 workers.
At this time, the queen starts producing the first reproductive individuals. Fertilized eggs develop into females (called "gynes

Diet and feeding
Adult hornets and their relatives (e.g., yellowjackets) feed themselves with nectar and sugar-rich plant foods. Thus, they can often be found feeding on the sap of oak trees

Hornets frequently fly into orchards to feed on overripe fruit, and tend to gnaw a hole in fruit to become totally immersed in its pulp.

developing in the nest, rather than consumed by the adult hornets. Given that some of their prey are considered pests, hornets may be considered beneficial under some circumstances.
The larvae of hornets produce a sweet secretion containing sugars and amino acids that is consumed by the workers and queens.
Predatory strategies
Hornets' ability to prey upon honey bees is favored by a number of adaptations. ''Vespa'' have a larger body size compared to their prey, a heavy exoskeleton to resist bee attacks, and strong mandibles and venomous sting. As concerns hornet hunting strategies, it has been demonstrated that some species such as '' V. tropica'' and '' V. velutina,'' can use both visual and olfactory cues for the long-range detection of honey bee colonies. Foragers of ''V. tropica'' can readily associate color and shape with potential food sources and exhibit color generalization. ''V. velutina'' foragers visually distinguish between bee dummy bait and cotton ball dummy bait, both treated with bee odors, preferring bee dummies. Foraging hornets are also selectively attracted to honey bee colony odors, in particular honey and pollen, as well as honey bee pheromone

'') honey bees, and its antennae respond to this compound. Intriguingly, this hornet attraction to honey bee pheromone is also exploited by the orchid '' Dendrobium christyanum'', which mimics the honey bee alarm pheromone in its flowers' scent to attract hornets that visit and pollinate the flowers. It is therefore likely that bee-hunting hornets visit the non-rewarding flowers in search of prey.
