Feeding and diet

The Mud-dauber Wasp is usually seen feeding on flower nectar but occasionally found flying with a spider held in its jaws, destined to be fed to larvae in a mud nest.

Life history cycle

Normally the Mud-dauber Wasp puts several paralysed spiders in each nest with one egg, to eat when it hatches. The adults are often seen collecting water and mud for their nests, which they commonly construct in protected areas of houses, buildings and rock overhangs.

Danger to humans

The Mud-dauber Wasp can deliver painful stings, but attacks are rare. An ice pack may be used to relieve the pain of the sting. If there is evidence of an allergic reaction, medical attention should be sought.
