Myrmica scabrinodis

Myrmica scabrinodis is a Euro-Siberian species of ant. It comes in a variety of forms that can be impossible to distinguish morphologically. As such, it has been suggested that the species is ongoing a major speciation event. Its colonies are monogynous or have only a few queens and may contain about 2500 workers. This ant species is the main host of the entomopathogenic fungus Rickia wasmannii. Phengaris caterpillars are primary threats of M. scabrinodis with specific species such as Phengaris arion developing a predatory relationship.
