Origin: Venezuela.

Scientific nameLucihormetica grossei

Common name: Mega Glowspot Cockroach, Mega Glowspot Roach.

Lucihormetica grossei, with its common name Mega Glowspot Cockroach, is the largest of the glowspot roaches, with males reaching a length of 48 mm and females slightly larger at 60 mm. Lucihormetica grossei cockroach was relatively recently described, in 2003 by Ingo Fritzsche. Although the males are shorter than the females, they are wider. Lucihormetica grossei have the longest wings from the other two glowspots: Lucihormetica subcincta and Lucihormetica verrucosa, but they cannot fly as well. The wild caught roaches are much more difficult to breed, but fortunately captive bred specimens are available in the hobby, which are much more easier to keep and breed. Lucihormetica grossei roaches seem to be less skittish than other roaches in the genus Lucihormetica, and with their much larger size, makes them an interesting roach to have as a pet, as they are more suitable for handling.

Fun fact: as with the other glowspots, its common name means that their spots on the pronotum may glow in the dark if the roaches have access to bioluminescent fungi (mushrooms) in their diet.

Terrarium: keep ⅕ moist by spraying and/or with moss. The substrate can be a mixture of peat (without fertilizer) mixed with crushed rotting leaves, some coconut coir and a little sand. Make it at least 5 cm deep so that the nymphs can bury in when they need to. They also need hiding spots to go under and hide themselves during the day. These can be carton egg cases, cork bark, or hard bark from other trees.
