Queen wasps are the last to be hatched from an existing nest towards the end of the summer. Once they are mature, they will breed with a few males and store the sperm inside them. The young queen wasps will then search for a place to hibernate over winter. Once winter has past and spring is upon them, they search for an ideal place to create there own nests. Once the queen has found a place, the queen constructs a small nest from wood fibres. The queen then uses the sperm she stored from the previous year to fertilise her eggs. The first few eggs laid are sterile female working wasps to assist the queen in laying more eggs and to tend to the offspring. As the family of wasps grows, the nest is made bigger along with more offspring being produced. The queens sole job now is to lay eggs and can do so for the hole season if she has enough sperm stored. Close to the end of the summer, the queen wasps supply of sperms starts to run out.
