🐝 The end of the wasp nest — what actually happens ⁉️ The complete cycle. ♻️
A typical UK social wasp colony is annual. The nest usually begins in spring with a single queen and by late summer/autumn, the colony enters its reproductive phase.
1️⃣The original queen starts to decline.
Earlier in the season, the queen's main role is producing workers. As the colony matures, the emphasis changes from producing workers to producing the next generation of reproductive males and queens.
2️⃣ The colony produces drones (males).
Male wasps, commonly called drones, are produced specifically for reproduction. They leave the nest and seek out females to mate with. They don't have the same role as workers and do not survive the winter.
3️⃣New queens are produced.
Towards the end of the season, the colony produces new queens, which are larger reproductive females. These queens leave the nest and mate, generally with males from other colonies.
4️⃣The colony's priorities change.
Once the reproductive generation has been produced, there is little evolutionary benefit to maintaining the colony through the winter. The huge workforce that maintained the nest during summer begins to disappear.
5️⃣Food becomes increasingly scarce.
As autumn progresses, insect numbers and other natural food sources decline. Cooler weather also reduces wasp activity and foraging. This contributes to the gradual breakdown of the colony. This is why you can sometimes see wasps becoming particularly noticeable around fruit, sugary drinks, fallen fruit and other food sources during late summer and autumn.
6️⃣Workers begin to die naturally.
The workers have relatively short lifespans. As the season progresses, more workers die and aren't replaced at the same rate. The nest therefore gradually loses its workforce.
7️⃣Falling temperatures dramatically reduce activity.
Wasp activity is strongly influenced by temperature. As temperatures fall, the colony becomes increasingly inactive. Frost and prolonged cold conditions can effectively bring the remaining colony activity to an end. The important distinction is that the nest doesn't simply switch off overnight because of the first frost. It is a progressive decline caused by the changing season, temperature, food availability and the natural end of the colony's annual lifecycle.
8️⃣The remaining workers and drones die, followed by the original founding queen. The once-thriving summer colony eventually collapses, bringing the annual life cycle of the nest to an end.
🔟 The new queens are the survivors.
The newly produced, mated queens are the critical part of the cycle. Rather than remaining in the old nest, they leave and find sheltered locations where they can overwinter. They enter a state of reduced activity known as diapause. They may shelter in places such as vegetation, soil/leaf litter or other protected locations.The old nest is abandoned and becomes dormant and never used again.
🔟 Spring Arrives... the overwintered queen starts the cycle once again. When temperatures rise, the surviving queens emerge.
A queen finds a suitable location and begins constructing a small paper nest using chewed plant material mixed with saliva.
She lays the first eggs and initially raises the first generation of workers herself. Those workers then take over many of the jobs involved in: Foraging, Feeding developing larvae, Nest construction, Defence , Caring for the queen and brood
The queen can then concentrate primarily on egg production.
The colony grows rapidly through spring and summer, eventually producing hundreds or potentially thousands of individuals, depending on the species and conditions.
And then the cycle starts again. ♻️
So when you see a wasp nest becoming quieter in late autumn, you're witnessing the natural end of an annual social insect colony — while the next generation of queens is already preparing to start the cycle again next year.
