Headlight Cockroaches (Lucihormetica verrucosa)

Look at an adult male Headlight Cockroach and your eye goes straight to the two yellow-orange spots on its pronotum, sitting just behind the head against a dark body and looking for all the world like a pair of car headlights switched on in the dark. That resemblance is where the name comes from, and it is the first thing anyone notices. Lucihormetica verrucosa is a medium to large roach from South America, and on the male those twin markings are the whole draw.

Here is the honest part, because I would rather you bought this animal knowing the truth. The spots do not actually glow. Despite the name and a claim that has been repeated for years, this species is not bioluminescent, and it has no light-producing organs. A 2025 study confirmed as much, and the original 2012 bioluminescence claim, made for a related Lucihormetica, was never substantiated. What you have here are bright coloured markings that resemble headlights, not lights that switch on. Most keepers I talk to like knowing that, and to my mind the animal is striking enough without the myth.

As a display roach it more than earns its keep. The contrast of those warm spots against a near-black shell is eye-catching under normal room lighting, and because the animal is calm and slow-moving it tends to stay in view rather than bolt for cover the moment you lift the lid. If you take to this one, its sister species the Glowspot Cockroach carries similar markings, and it sits well alongside the marbled Centurion Porcelain Cockroach or the pale green Cuban Cockroach in a shelf of display species.

One thing worth knowing before you buy: only the adult males wear the headlights. Females are a plain, glossy dark brown, and younger nymphs of both sexes are unmarked, with the males developing their spots only at the final moult. In a small group you are really buying the promise of those spots as the males mature, so if you would rather start with a male or two, just ask and I will pick them out where I can.

Care is straightforward once the basics are in place. This is a warmth-loving tropical animal, so keep it at around 24 to 28°C, which means a UK home will need some gentle heating for much of the year, ideally a low-wattage mat on a thermostat fixed to the side of the enclosure rather than beneath it. Aim for fairly humid conditions of roughly 60 to 80%, and give the roaches a deep layer of substrate to burrow into, as they spend most of the day underground. I use our flake soil as the base, topped with bark hides and a generous covering of magnolia leaf litter, which they shelter beneath and slowly graze on.

Feeding is easy and undemanding. This is not a fast feeder roach that swarms its food, so I offer a little and often: vegetables and fruit for the bulk of the diet, with a protein source such as fish flake or dried insects added now and then. Females are ovoviviparous, which means they hold their eggs inside and give birth to live young, and the colony builds slowly and steadily rather than exploding the way some roaches do. Adults can climb glass and smooth plastic, so a secure, well-ventilated lid is essential. Being tropical, it cannot cope with our climate and has no chance of establishing outdoors in the UK.

Every animal I send is captive-bred, packed double-walled around a ventilated tub of damp sphagnum and posted Monday to Thursday by tracked next-day Royal Mail. A live-arrival guarantee and a 20% overcount come as standard.
