Just one lone Paper Wasp was busily building this nest under the handrail on OlderSon's verandah. The nest is made out of wood fibre and was firmly anchored to the wood by a thin stem called a petiole.
Some of the cells already contained larvae, and there's one white grub visible, working hard to close the door on his cell, no doubt looking for some peace and quiet.
We had to knock the nest down, can't have a colony of wasps around with curious Callum close by, but the queen wasp angrily searched for her babies for a long time before giving up.
I sincerely hope she moves to a different neighbourhood to start her next family.
