…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.
Hey look, it’s Euzosteria subverrucosa, one of my favorite native roaches. I’ve only seen them twice before, in Piara Waters, in Banksia scrub, and in Hammond Park, near Casuarina scrub. This one was in dunes at Secret Harbour. Isn’t she a cutie.

Cockroaches are part of the superorder Dictyoptera with their close relatives the mantids and termites. The similarities between roaches and mantids can be seen in the triangular heads and laying of oothecas. Recent DNA testing has led some people to consider termites to be part of the order Blattodea with the cockroaches because of the very close similarities with wood-eating roaches in the Cryptocercus genus.

A harmless species that lives among mulch or sometimes inside walls, and frequently wanders into houses. This one was hiding inside the joint of a bookshelf I was dismantling. Isn’t he, or she, wonderfully shiny and flat.
