Red Slug Caterpillar Moth

This moth has a beautiful, almost shining green and blue coloration. Its front wings are 28–35 mm in length. It flies mainly during the daytime, feeding on the nectar of flowers, but males will also fly to lights at night. In Japan, it is distributed in Honshu (Izu Peninsula and westward), Shikoku, Kyushu, Tsushima, and other areas. It is a southern insect, but has been known to inhabit Dōgo Island for a long time, making it a noteworthy species in terms of distribution. When stressed, it produces a foul-smelling fluid from its thorax.
