A new host record for the sawfly Monostegia abdominalis (F.) was obtained in Quebec. The host plant, terrestrial loosestrife (Lysimachia terrestris (L.) BSP), was abundant on a lake shore due to regular flooding, enabling the sawfly to reach a high population level. Two generations occurred each year. The immature stages and aspects of their behaviour, and female oviposition behaviour, are described.
