Wasp (Mason) Pison spinolae
Scientific name: Pison spinolae
Common name: Mason wasp, Mason Bees
Pison spinolae is a native species of wasp, about 16 mm long found throughout New Zealand. The adults eat nectar. The female mason wasp builds a nest of cells out of mud and while doing it she makes a whining noise. She paralyses a spider then takes it back to her nest. She lays an egg in each cell and a grub hatches from the egg and consumes a helpless but still living orbweb spider. The orb spider is the fat triangular spider that makes those beautiful shaped webs you see on misty mornings.
