Shedwood Forest, Tapawera, January (Miss Stella Hudson); one specimen. This seemingly obscure but really beautiful little insect (the smallest of the 154 New Zealand Oecophoridae) is probably adapted by its complex marking and rough scaling for concealment on tree-trunks, and by its bright metallic and coppery ornamentation for flying in sunshine, both these habits being characteristic of the species of Petalanthes also.
