Tiny cricket in sufferance

At the end of March I willingly would have liked to shoot arthropods in the wild, such as flies, midges or early beetles. Due to the unusually long, never-ending winter in Central Europe I had poor chance to find any active insects, although in this period we could observe several species of butterflies and many-many flies, or small weevils and ground beetles. So I decided to join friends looking for overwintering beetles hidden under barks of deciduous and coniferous trees or still in the pupal chambers within the wood.

Now instead of beetles and flies I would introduce a tiny particular orthopteran living together with ants. The ant-loving cricket (Myrmecophilus cf. acervorum) has a really specific life related to ants, giving them nothing in exchange of food and safe living space. I propose an article on Wikipedia, where the summary of the knowledge about them is described well.

A mixed deciduous forest with fallen trees in central Hungary. The big rotten tree was an oak (Quercus petraea). We expected and found click beetles (Ampedus spp.) and small stag beetles (Aesalus scarabaeoides) in the red rot, and sometimes opened huge cavities with hundreds of Lasius emarginatus (ID-cred: G. Lőrinczi – see his comment) ants.

Between the ants there was another insect at the same size but remarkably different appearance:

It was walking quietly without any incident with the ants:

Definitely the smallest (3 mm) and most interesting cricket in Europe:

Probably they don’t need to see too much that’s why have degenerated eyes with only a few ommatidia:

The macro photos were taken with a Canon MP-E65 1-5x maro objective at various magnifications and cropped subsequently as much as needed. Each one was handheld and lit with diffused external flash (Canon Speedlite 270EX). Some of the photos will be uploaded soon onto Flickr.

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.

Another one, looking to be starving:

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