Beetle in the cave

As a macro-photographer, I have a wishlist what I would like to see and shoot from the world of arthropods. One of the targets was the endemic ground beetle Duvalius gebhardti found only in a small mountain range in Hungary. Its way of life is still unclear. All we know that adults live in narrow caves and crevices in the karst.
I visited one of the known habitats, a cave in the Bükk Mountains with young biologists and a caver, and luckily, we found a few living individuals. Now let’s see the pictures of the short excursion. Some of the photos were taken by a member of the team, Márton Szabolcs.

Weird company walking to the cave.

Ouch, this is really strait! Claustrophobics turn back!

On the walls we could see large parasites of the bats. These ticks (Ixodes vespertilionis) differ from the common ones in their long legs.

The highlight of this trip – the tiny, 4 mm long Gebhardt’s blind ground beetle (Duvalius gebhardti):
