Lasius umbratus is a fascinating parasitic ant species. They invade existing nests, spread their scent, kill the resident queen, and take over the colony. In the wild, they nest in moist soil in open woodlands, forests, and fields. Lasius umbratus is monogyne, meaning there can only be one egg-laying queen in the colony. Colonies can grow up to 2,500-5,000 workers. These ants have nuptial flights from July until September, where new queens fly out to meet and breed with ants from other colonies. Workers are 3 to 6 mm long, and queens are around 8 to 9 mm long.
