Lucihormetica luckae

…is a unique species of “giant cockroach” (Blabridae) which has been collected around the Tungurahua volcano in Ecuador. Lucihormetica luckae is noted among cockroaches for its ability to bioluminesce via two spots on its back carapace which are inhabited by bioluminescent bacteria. It is though that this ability evolved to mimic the appearance of the toxic click beetles of the genus Pyrophorus. It is also though that L. luckae might be the first known species to use bioluminescence as a form of defensive mimicry.
