Wasps - annual life cycle

For many social wasps, the colony has an annual life cycle:

• 🐝 Spring: A fertilized queen that survived the winter emerges from hiding. She startsa brand-new nest, usually by herself.

• 🐣 Early summer: She lays eggs. The first workers hatch and take over nest-building, feeding larvae, and defending the colony.

• 📈 Summer: The colony grows dramatically, sometimes to hundreds or thousands of wasps.

• 👑 Late summer/autumn: The colony produces new queens and males. They leave the nest and mate.

• ❄️ Winter: The old queen, workers and males generally die. The nest is abandoned.

• 🌱 Next spring: The newly fertilized queens emerge from their winter shelters and each starts a new colony somewhereelse.

So the important part is that the species doesn't need the nest to survive—the genes do.

Think of the old nest as a temporary nursery rather than a permanent home. The next generation of queens carries the colony's lineage into the following year and starts thecycle again.

Interestingly, this is also why destroying an old, abandoned wasp nest usually doesn't prevent wasps returning next year. The new queen isn't normally coming back to that nest; she's starting from scratch.

There are some exceptions: certain wasp species have perennial colonies or different social systems, but the familiar German wasp in Ireland generally follow the annual pattern above.

So if you see a solitary wasps hiding somewhere sheltered in winter, Leave her alone :)
