Slime Mould – Blob (Physarum polycephalum)

Physarum polycephalum, commonly known as the “Blob,” is a species of slime mould widely recognised for its distinctive yellow colour and rapid, web-like growth. It’s one of the most popular and reliable food sources for high-end springtail species, though it can also be fed to other springtails and microfauna.

When provided with a mild carbohydrate source such as oats, Physarum forms visible, branching networks that efficiently explore its environment. It thrives in warm, humid conditions and is easy to maintain on agar or other moist substrates.

Key Points:

  • Excellent primary food source for high-end springtail species

  • Suitable for most springtails and other microfauna

  • Grows rapidly under warm, humid conditions

  • Ideal for culture maintenance or observation

Usage Instructions:
Place a small piece of Physarum onto prepared agar or damp substrate and feed with oats or another mild carbohydrate source. Keep in a dark, humid environment to encourage steady growth. Maintain moderate moisture levels and avoid direct light.
