Jewel beetle on hydrangea

A jewel beetle on a hydrangea leaf.

I think his metallic iridescent body isn't suitable for mimicry.

In Japan, this insects were used for decoration of buildings long ago.

Front.

His face was prettier & more beautiful than other insects. 

Hydrangea

The big flowers surrounding little buds are ornamental flowers.

They have no abilities for reproduction.

They're accessories for little flowers in center.
