Also known as Lucihormetica luckae, the glow-in-the-darkcockroach is a species of giant cockroach, which can be found in the south American mountain, Tungurahua. Its back carapace features two large and one small spots inhabited by bacteria that glow when exposed to fluorescent light. The evolutionary purpose of this bioluminescence is likely to mimic the appearance of the toxic click beetle that emits light at the same wavelength.
