Little Carpenterworm

A smaller relative of the carpenterworm moth that bores into oaks and other hardwoods. Larvae create long tunnels through the sapwood and heartwood.

Its tunnels reduce the commercial value of lumber and provide entry points for wood-decay fungi.

Japanese Lunar Moth

A beautiful pale green moon moth found in Japan, known as 'o-mizuao.' Features long, elegant tail streamers on the hindwings. Closely related to the Luna moth of North America.
