Myrmecophilus acervorum (Panzer, 1799)

Nutrition:
Apparently the species feeds on ant brood and rotten plants. The animals are obviously partly fed by the ants.

Habitat:
Mostly Myrmecophilus acervorum inhabits warm, dry habitats such as quarries, margins of nutrient-poor grasslands and open forests. On the other hand, Myrmecophilus acervorum has also been found in settlements.

Life cycle:
Imagines are found year-round. They live in ant nests, particularly in those of Lasius species such as Lasius flavus. It can be found most easily by turning over stones, especially in the morning or in late April or May and again in late summer, when the stone bases are not too warm and well staffed with ants.

Endangerment: U

Endangerment factors:
The risk is difficult to assess. But at least the dry grassland habitats are in danger (habitat changes with respect to the micro-climate).

Remarks:
Myrmecophilus acervorum occurs from France to Russia. The situation in the Mediterranean is obviously not finally solved due to similar species and determination difficulties.
