Field-guide notes
Southwestern North American desert environments.
Roughly 18–22 mm for typical adults.
Powdery blue to blue-gray surface caused by a waxy cuticular coating; darker when wet.
Diurnal to crepuscular surface-active beetle; freezes and curls defensively when disturbed.
70–85 °F (21–29 °C), with a warmer daytime zone and no requirement for tropical humidity.
Arid to dry. Keep the adult enclosure dry with good ventilation; provide moisture mainly through food and controlled micro-sites.
Dry sand/soil mix with rocks, bark, and secure hides.
Omnivorous scavenger: dry plant material, vegetables, small amounts of fruit, and occasional protein sources.
No special calcium requirement comparable to millipedes/isopods; offer a varied omnivorous diet with modest protein.
Adult care is straightforward, but successful larval rearing is substantially more demanding and benefits from controlled substrate moisture/temperature.
Slow/technical in captivity compared with simple adult maintenance.
Primarily a display/scavenger beetle for arid setups, not a high-output cleanup-crew species.
Beginner for adults; advanced for breeding.
The blue appearance is structural/waxy rather than blue pigment, and handling or moisture can temporarily darken the surface.
