Paper Wasps

Constructing a nest on a roadside fence post.
Philippa's  (Apollo Fly) suggested theme for today's MM challenge is Shape.
 Paper wasps are pests and have wiped out entire populations of Monarch butterflies in some areas but their nests are amazing. The shape of each cell allows it to fit neatly next to the neighbouring cells.
Thank you, Philippa, for hosting MM in March.                                                                                                                                                                                                                                                                      .
