Mega Glowspot Roach
About the Species
Lucihormetica grossei is a rare, slow-growing roach species known for the two bright orange “glow spots” on adult males. These roaches are native to South America and are primarily a display species. They are docile, quiet, and more about the looks than the action. And no, the glow spots don’t actually glow… they just look cool.
Male vs Female
Males: Smaller, fully winged, and show off the bright glow spots on their pronotum (shoulders).
Females: Larger, wingless or with tiny wing stubs, and lack glow spots entirely.
Both sexes are gentle and make great hands-off pets.
Enclosure Setup
Basic Setup:
Enclosure Type: Acrylic/glass enclosures or a plastic tub with a secure lid and ventilation.
Ventilation: Good airflow is important.
Size: A 2.5 - 5 gallon enclosure is fine for a few, larger enclosures (10 gallon+) for colonies.
Decor & Hides:
Cork bark slabs or stacked bark for hiding and climbing.
Leaf litter is appreciated for cover and enrichment.
Substrate:
Use a moist substrate that holds humidity well (NOT Coco Fiber)
Add leaf litter or sphagnum moss on top.
Keep it damp (not soaked) to maintain humidity.
Temperature & Humidity
Temperature: 75–85°F is ideal. A heat mat on the side can help if your room runs cool.
Humidity: 60–80%. Mist once or twice a week depending on ambient levels.
Water: Provide a small shallow water dish with a cotton ball, water crystals, or use fresh fruit as a moisture source.
Diet
These roaches are scavenging omnivores. Variety is key.
Staples: Leaf litter, roach chow, dry dog or fish food.
Fresh Foods (rotate): Apple, banana, cucumber, carrot, zucchini, leafy greens.
Calcium: Occasionally offer crushed cuttlebone or powdered calcium for health.
Pro Tip: Don’t overfeed produce. Remove uneaten food within 1–2 days to avoid mold or gnats.
Quick Notes
They are slow growers, so patience is key.
Non-climbers: They can’t climb smooth plastic or glass, but still keep a secure lid.
Completely harmless - no biting, no odor, no noise.
Great for display, education, or just for people who think glowing roaches are rad.
