Cyclocosmia ricketti, often called the Chinese Hourglass Trapdoor Spider, is one of the most unusual spiders you’ll ever come across. Its rounded, patterned abdominal disc looks almost like a carved coin, and it uses this incredible structure as a natural shield. When startled, the spider slips into its burrow and seals the entrance with the disc, creating a perfect little “door” that blends into the soil. It’s a fascinating behaviour to watch and one of the reasons this species is so sought after.
 
In the wild, this spider lives in parts of southern and central China, usually on forested hillsides with firm, clay‑rich soil. It spends most of its life hidden underground in a deep, silk‑lined burrow, only emerging at night to feed. Because of this secretive lifestyle, people rarely see them in nature—most sightings happen after heavy rain when they’re temporarily forced above ground.
 
In captivity, C. ricketti is a calm, slow‑moving species that prefers a quiet, stable environment. Given deep, compactable substrate, it will quickly build a burrow and settle in. Keepers often see only the neat, round plug at the entrance, but that’s part of the charm—this is a species that behaves almost exactly as it does in the wild. For anyone who enjoys observing natural behaviours and appreciates spiders with truly unique adaptations, Cyclocosmia ricketti is a remarkable and rewarding species to keep.
