Eureka!And there are spiny things growing from your back....Let's have a looksie...I shall be the one to reveal your true identity!!Hmm...
Pitch black, aren't you?...Your true identity is a Spined Spineless Spiny-Spiny, isn't it?!! The Japanese name for leaf-mining beetles (subfamily Hispinae) is "spiny leaf-beetles" (toge hamushi), but they used to have the alternate name "spiny-spiny" (togetoge). A few species of leaf-mining beetles have no spines, leading to the amusing name of "spineless spiny-spiny" (although the preferred term is hosohirata hamushi, "thin flat leaf-beetle") ...and sure enough, a species of hosohirata hamushi with spines was recently discovered in Southeast Asia, and promptly nicknamed the "spined spineless spiny-spiny" (togeari togenashi togetoge).
