Showy Headshield Slug

This headshield slug is also referred to as Philinopsis cyanea, Aglaja cyanea and Doridium cyanea.

This very attractive slug has variable coloration, from a light translucent brown to opaque dark brown (even black). There are two parallel lines (yellow to orange-brown) running down either side of its midline, and often another pair further out (like in this individual).
