Abstract
    Saldula palustris inhabits estuarine salt marshes along the Oregon coast. There are three generations per year. Adults migrate from the intertidal zone and over winter. Reproductive diapause during the winter is facultative. Adult insects return to the intertidal site in January and nymphs are present from April until October. The insects are aggressive predators and cannibalism is common. They tolerate daily tidal submergence periods of up to 9 hrs duration. They do retreat before the incoming tide and remain quiescent when submerged. S. palustris is considered a transitional form with behavioral but as yet limited structural adaptations to aquatic life.
