A group of cockroaches from Brazil is purported to release bioluminescence through a pair of eye-like cuticular structures on the pronotum (Vršanský et al. 2012). Because living specimens taken from their natural habitat are rare, the authors examined dead material. It is my opinion that the methods employed provide no direct evidence that the insects are indeed bioluminescent; rather, the authors base their conclusions about bioluminescence in the genus Lucihormetica on two factors: (1) a… 
Luminescent system of Lucihormetica luckae supported by fluorescence lifetime imaging
There is no way to prove the bioluminescence in the species that might be extinct, except for finding a living alight individual, and the validity of the L. luckae holotype thus lies on autofluorescence (AF) measurements.

To facilitate future research in this field, the recent attempt, the bioluminescent organism DNA barcode initiative is introduced, which will provide resources for other scientists to efficiently identify unstudied biolUMinescent organisms, focus their biochemical and genetic research goals, and will generally promote biolauminescence as a field of scientific study.

In this chapter, a general review on the fluorescence in terrestrial animals is made, including their systematic distribution, research history, fluorophores, and proposed functions for each group among several other aspects.


Light-mimicking cockroaches indicate Tertiary origin of recent terrestrial luminescence
This work presents a geographical distribution of only the third order of luminescent insects—luminescent cockroaches, with all 13 known and/or herein reported new living species (based on deposited specimens), and shows that, for the first time, photo-characteristics of three examined species are nearly identical with those of toxic luminecent click beetles, which they mimic.
Xenorhabdus and Photorhabdus spp.: bugs that kill bugs.
Xenorhabdus and Photorhabdus spp. are gram negative gamma proteobacteria that form entomopathogenic symbioses with soil nematodes. They undergo a complex life cycle that involves a symbiotic stage,

Detailed three‐dimensional visualization of resilin in the exoskeleton of arthropods using confocal laser scanning microscopy
The results clearly show that all resilin‐dominated structures, which were visualized successfully using wide‐field fluorescence microscopy (WFM) and a ‘classical’ UV excitation, could also be visualized efficiently with the proposed CLSM method, which has several advantages over WFM with respect to detailed morphological imaging.
Three‐dimensional graphic reconstruction of the insect exoskeleton through confocal imaging of endogenous fluorescence
The exoskeleton of the cockroach leg was imaged via confocal microscopy to generate digital graphic reconstructions of its three‐dimensional structure that showed that strain sensing mechanoreceptors are located in association with buttresses and thickenings that form a consistent internal architecture in both juvenile and adult animals.
