What do wasps eat?

What do wasps eat? It changes according to the time of year.

Wasp grubs need a diet mostly of protein and they are fed on insect prey brought in by foraging workers.

The workers need mainly energy foods such as carbohydrates, and so favour nectar and sweet substances such as fresh and processed fruits.

The queen wasp is fed on a mixture of nectar, fruit, and meat juices.

By Autumn the larval wasps are fully fed and brought up, and the workers retain all the food they collect for themselves. They become increasing keen for sweet foodstuffs such as fruit and man made sweets and drinks, and can become drunk as a result of over consumption of ripe and fermenting fruit.

This is when they are at their most annoying, and when we are most likely to get a wasp sting.
