Tetrodontophora bielanensis

is the largest springtail species in Europe, native to forest regions of Central and Eastern Europe. It is known for its dark, glossy body and its ability to release a strong, pungent defensive secretion when disturbed, giving it a notable presence among microfauna keepers. Despite its size for a springtail, it is completely harmless to handle indirectly.

These insects are non climbing, hardy, and detritivorous, making them suitable for keepers looking for a low maintenance bioactive cleanup crew or an interesting springtail culture on its own.
