Life in the Notranjska Regional Park is extremely diverse even beneath the surface, where, among other specialised cave dwellers, lives the narrow-necked blind cave beetle (Leptodirus hochenwartii), the first described cave beetle in the world.
This beetle has no eyes and pigment, and orientates itself in eternal darkness with long antennae and legs sensitive to vibrations. In this way it avoids dangers that lurk in the dark. The greatest threat comes from the surface in the form of pollution and organic loading of waterways, which sink into its world, and collectors who persistently remove beetles and other animals from caves ...
Narrow-necked blind cave beetle is notable not only from the perspective of nature, but also from the perspective of history, as with its discovery Slovenia became the cradle of speleobiology. Therefore our task, to keep its home untouched, is all the more binding.
