    Specific Biology

    This blackish and shy species is found in the boreal coniferous forest and in similar biomes in the mountains of North America where it builds large sandy or loamy mounds with huge polygynous populations (Francoeur, 1973). These mounds may be naked or covered by mosses or herbaceous plants.
