Cryptoglossa variolosa – Black Death Feigning Beetle
Dramatic name, charming personality. The Black Death Feigning Beetle (Cryptoglossa variolosa) is a native North American darkling beetle found across the arid deserts of the American Southwest — a tough, long-lived, and endlessly entertaining invertebrate that has earned a devoted following in the hobby. When threatened, this beetle flips onto its back and plays dead with theatrical commitment — a defense behavior so convincing it gave the entire group their unforgettable common name.
Matte black, rugged, and surprisingly personable, C. variolosa is one of the best beginner invertebrates available — and a perennial favorite for display enclosures, bioactive setups, and anyone who wants a low-maintenance pet with genuine character.
