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.

“Six-spotted Cockroach” (Eublaberus distanti

Also known as the Four-spotted Cockroach or Trinidad Bat-cave Cockroach, the six-spotted cockroach is a species of Blaberid cockroach that is native to Trinidad and Tobago, Guatemala, Costa Rica, Panama, Colombia, French Guiana, Suriname, Guyana, Brazil, and Peru. Six-spotted cockroaches typically are observed in relatively dry guano-rich areas in caves (thus the name “bat-cave”) but are also found in rotting logs, decaying litter and epiphytes. Like many other cockroach species, E. distanti is a scavenger feeding on any animal or vegetable matter readily available.
