Most species of social female and male wasps mate once a year. After mating, female wasps hibernate in the ground or in an enclosed space until the winter passes. The males die. In the spring, a fertilized female wasp starts her colony by laying eggs in cell-like pods.
Larvae hatche from the eggs and are fed by the female. Adult workers emerge 10 days later and care for the additional eggs. Some female worker wasps are sterile, their sole purpose being to nourish the baby wasps and assist the queen. As the spring progresses, more eggs, larvae and workers are produced.
Near the end of summer, male wasps grow from the unfertilized eggs. Fertile females develop from the well-fed larvae. The insects mate and the process begins again. For wasps that live solitary lives, all females are fertile. Female solitary wasps commonly lay their eggs near a spider or other insect that the wasp has paralyzed with venom.
The mother wasp does this so that as larva develops, it can use the insect for food. Some solitary females watch over their nest, while others abandon them. Male and female solitary wasps mate in the spring. Social wasps are one of the most complex animal societies known where all members of the nest co-operate. Workers help raise the offspring of the reproductive queen, but also collect food and defend the nest.
Life cycle of [Vespula] species. A nest begins The queen wasp awakes from hibernation in the spring. After a short period of feeding and exploring, she begins to build a nest in a dark and dry place. She usually chooses a warm spot, often in a bank with a sunny aspect, but also in attics, house roofs, eaves, or walls, and can fly up to 70 km in search of the perfect nest site.
She builds a honeycomb-like cell structure out of wood fibre. The queen gathers sugary substances and catches other insects for protein to feed the larvae. After five moults over about 15 days each larva spins a silken cap over the cell and pupates. Pupation takes days before an adult worker wasp emerges. In total it takes approximately days from egg to adult, although the length of time spent in each stage is determined by environmental conditions.

Once these new queens and have hatched and pupated into fully formed Queen Hornets, they leave the nest and fly off to search for Male Drones from other nests to mate with.
Once mated, these new queens will search out a suitable place to hibernate over the winter. The whole cycle starts again in the spring, where each of these new queens will build a new nest.
After the new Queen hornets have left the nest no other eggs are laid by the original queen. When the first frosts arrive and the temperature drops, the nest starts to die off.
Some nests survive longer than others if they are located in warm loft spaces but usually by Christmas the nests are dead. All the worker hornets and male drones along with the original queen will have died.
Hornet nests are usually more significant than a wasp nest , but the amount of individuals contained within the nest is much smaller than a wasp nest typically between Hornets per nest.
