Beetle, Therea petiveriana, The Domino Cockroach Specimen from Sri Lanka.

You will receive this specimen or one like it.

Meet Therea petiveriana, the charming Domino Cockroach from Sri Lanka—a species that proves not all cockroaches deserve a bad reputation. Far from being a pest, this elegant insect is admired for its striking black-and-white pattern, which resembles a set of domino tiles scattered across a glossy shell.

The pattern isn’t just for show—it’s a clever form of aposematic mimicry. Those bold white spots warn potential predators that this cockroach might be distasteful or toxic, even though it isn’t. This bit of visual trickery helps it survive among the dry leaf litter and forest debris of Sri Lanka’s lowland regions.

Unlike its household cousins, Therea petiveriana is clean, slow-moving, and non-destructive, spending its days sifting through decomposing plant material. In doing so, it plays a quiet but vital role in recycling nutrients back into the soil.

Collectors and educators prize this species for its beauty and calm temperament—an unexpected ambassador for the cockroach family that challenges how we think about these ancient, adaptable insects.
