Variegated False Darkling Beetle (Platystomos albinus)

Platystomos albinus, commonly known as the Variegated False Darkling Beetle, is a distinctive beetle in the family Tenebrionidae. This beetle is known for its unique appearance and interesting behaviors.


  • Size: The beetle typically measures between 8 to 14 millimeters in length.
  • Coloration: The variegated false darkling beetle has a striking black and white patterned body. The elytra (wing covers) feature a distinctive pattern of black and white patches.
  • Body Shape: They have an elongated body with robust and somewhat flattened elytra. The head is proportionally small with strong mandibles.


  • Preferred Habitats: This species is often found in deciduous and mixed forests, particularly in areas with abundant decaying wood and leaf litter.
  • Geographic Range: Platystomos albinus is widely distributed across Europe and parts of Asia.


  • Diet: Adults and larvae feed on decaying wood, fungi, and sometimes small invertebrates found within their habitat.
  • Reproduction: Females lay eggs in decaying wood. The larvae develop inside the wood, feeding on the decaying material until they pupate and emerge as adults.
  • Activity: These beetles are primarily active during the warmer months, usually from spring to early autumn.

Interesting Facts

  • Mimicry: The striking black and white pattern may serve as a form of mimicry or camouflage, helping the beetle blend into its environment and avoid predators.
  • Larval Development: The larvae play an essential role in the decomposition of wood, contributing to nutrient cycling within forest ecosystems.
  • Adaptability: This species is adapted to a variety of forested environments, including both natural and managed forests.

Conservation Status

  • Population: Platystomos albinus is not currently considered threatened and is relatively common within its range.
  • Conservation Efforts: Maintaining healthy forest ecosystems with plenty of dead wood and decaying organic material supports the populations of these beetles.

Identification Tips

  • Coloration: Look for the characteristic black and white patterned elytra, which is the most distinctive feature of this beetle.
  • Size and Shape: Note the beetle’s elongated and somewhat flattened body, along with its robust build.
  • Habitat: Found in deciduous and mixed forests, often in association with decaying wood and leaf litter.


Platystomos albinus, the Variegated False Darkling Beetle, is a notable member of the Tenebrionidae family, easily identified by its unique black and white coloration. Found in forests across Europe and parts of Asia, this beetle contributes significantly to the decomposition of wood and nutrient cycling within its ecosystem. Its distinctive appearance and important ecological role make it a fascinating subject for study and observation.
