Natural Habitat

Arid and semi-arid desert regions of the southwestern United States and northern Mexico

Diet & Feeding

Opportunistic omnivores, feeding on decaying plant matter, fungi, seeds, and occasionally small insects. In captivity, they eat various fruits, vegetables, and commercial beetle foods.

Behavior Patterns

Diurnal, but often active during cooler parts of the day or twilight. Known for their 'death-feigning' behavior when threatened, where they play dead by flipping onto their backs and remaining motionless. Their blue color comes from a waxy coating that helps reflect UV light and reduce water loss. They are slow-moving and long-lived for an insect, often living several years.

Risks & Benefits

No known risks to humans. As detritivores, they play a beneficial role in their ecosystem by breaking down organic matter, contributing to nutrient cycling. They are also popular and low-maintenance pets.
